Abstract

Kernels are designed in different configurations based on design propertied of an enclosure or other requirements. A prism assembly having various types of filters, waveplates, beam splitters (e.g., path length matched beam splitters) and/or other optical components are provided to selectively direct light beams to each of red, green, and blue microdisplays that manipulate the light and then combine the manipulated lights into an output image. The prism assembly includes an input face, an output face, and other faces on which the microdisplays are attached in a number of different configurations. Requirements and exact placement of optical components varies depending on which microdisplay is attached to which face. The components of the prism assembly may be arranged in path length matched positions.

In an embodiment, the second quadrant is diagonal to the fourth quadrant, the input surface is adjacent to the fourth surface, and the output surface is adjacent to the third surface. In another embodiment, the second quadrant is diagonal to the fourth quadrant, the input face abuts the first face, and the output face abuts the third face. Red, green, and blue microdisplays are attached to each side of the stack, and corresponding additional optical components, such as waveplates and filters, along with the splitter are placed in the stack In each important position, a corresponding beam is directed to each of the microdisplays. The drawings show the most useful combinations and preferred configurations of the various optical components, however, those of ordinary skill in the art will readily appreciate other combinations and configurations upon reference to the disclosure of the present invention. In one embodiment, the beamsplitters include beamsplitters that have equal path length matching through the beam path of the beamsplitters. Moreover, the components of the 稜鏡 combination including any of the beamsplitters can be placed at positions where the path lengths through which the entire 稜鏡 combination are equal are matched. 1261684 193⁄4^23⁄413⁄4 I _None (5) — For implementations, please refer to the figures 'where the same code indicates the same or the corresponding part, especially see Figure 2' which shows a light management system (LMS) The core (200), and the figure shows a possible configuration of the ray path and components to which a combination of the invention can be applied. Path length matching and other features are provided in accordance with the present invention. The core (2〇〇) consists of a prism combination (2 0 1 ), and a number of attached microdisplay green “microdisplays” (23 0 ), ''red' microdisplays (23 2 ), and “blue” microdisplays (234), wherein the color is placed in the quotation marks because the color identifies the content of an image to be displayed by the individual microdisplay, or the light to be manipulated by the individual microdisplay. This core is a basic component of a projection system. The tantalum assembly (201) includes a set of optical components, films, and matching components that are used to form a single unitary unit. A white light (205) is directed to a Polarizing Beam Splitter (PBS) (210). A polarization beam splitter film (215) vertically polarizes the white light and splits the white light into two polarized beams (220) and (240). The ray paths through the 稜鏡 combination are separately labeled to indicate the color and polarization of each light path. For example, incident white light (2 05 ) is labeled W S + P (meaning white S and P-type polarization); beam (220) is initially labeled as WS (meaning white, s-type polarization). The s-type polarized white light (220) passes through a green dichroic filter (221) and a cleaned polarizing plate (221B) (such as a Mostek polarizing plate), and the cleaned polarizing plate (221B) is used to remove the self-film (215). Any reflection does not need -10- 1261684 1 丨 'no %w»n· I awawnBifMUHWi rum r fr P-type polarized light (dichroic filter (22 1 ) and cleaned polarizer (221B) through green light The beam (220) is made into a green s-polarized beam (and labeled as GS)). The green s-type polarized beam enters a second beam splitter (2 1 2 ). A polarization beam splitter film (2 1 7) reflects the s-type polarized green light to the "green" microdisplay (23 0 ). The ray path is marked as: W for white, R for red, G for green, and B for blue. The polarization is indicated by S for S-type polarized light and P for P-type polarized light. In addition, Y is used to indicate yellow, and C is used to indicate cyan. The green microdisplay (230) manipulates the polarized green light based on the green content of an image to be displayed. The ''green'' microdisplay modulates the polarization of the green light in a pixel-by-pixel manner. For example, a pixel that does not change the green content of the image to be displayed will rotate the polarization of the pixels of a strong green content of the image to be displayed by 90° and rotate the polarization of other pixels of various levels of green content. Various angles proportional to the amount of green content. The microdisplay also reflects the (now modulated) green light back toward the polarizing beamsplitter film (21 7) (the polarization manipulation of the microdisplay reflects the light or other polarization effects). The polarizing beam splitter film (217) then reflects portions of the green light and passes through other portions of the green light. The ratio between the amount of reflected light and the amount of passing light is based on a modulation performed on the reflected green light.

圖 2 之組態示出由 4個以相同方式建構的 PB S 所製成之一稜鏡組合，此種稜鏡組合優於採用執行各種功 能的光學組件（因而有各種不同組態的光學組件）之系 統，這是因爲以相同方式建構的各 PBS減少了零件的數 目、及一特定光學設計中各組件的不同功能。因此，對應 的生產線將有規模經濟及較低的庫存量等效益。然而，我 們亦可看出：可利用各光學元件的許多不同組合使各種光 束正確地反射或通過，然後重新結合成最後的光束 (28〇 )。此外，可建構使用具有各種不同功能的光學組 件之稜鏡組合。而且如前文所述，可利用本發明所述之技 術及製程來建構具有所有這些變化（不同的尺寸、不同的 形狀、及不同的組態等）的稜鏡組合。 結合各光學組件，以便產生該等分光鏡。例如，個別 的棱鏡（206 )及（208 )是可結合而作出偏振分光鏡 (P B S ) ( 2 1 0 )之光學組件。在製造該稜鏡組合之前， 先作出該等分光之光學組件。稜鏡組合（2 0 1 )示出四個 分光之光學組件，亦即偏振分光鏡（p B s ) (210)、 -13- 1261684 卜5^7 j正 1 imKj 2 1 4 )、及（2 1 6 )。每一該等偏振分光鏡 (後文中將稱爲PBS )包含一偏振分光鏡薄膜（例如 2 1 5、2 1 7、2 1 9、及2 1 3 )。該等偏振分光鏡薄膜最好是 在該等分光鏡的對角線，並延伸經過該p b S的外表面所 界定的角。例如，偏振分光鏡薄膜（2 1 5 )沿著棱鏡The configuration of Figure 2 shows a combination of four PBs constructed in the same way, which is superior to optical components that perform various functions (thus having various configurations of optical components) The system, because each PBS constructed in the same way reduces the number of parts and the different functions of the various components in a particular optical design. Therefore, the corresponding production line will have economies of scale and lower inventory. However, we can also see that many different combinations of optical components can be used to properly reflect or pass the various beams and then recombine into the final beam (28〇). In addition, a combination of optical components having a variety of different functions can be constructed. Moreover, as previously described, the techniques and processes described herein can be utilized to construct a combination of turns having all of these variations (different sizes, different shapes, and different configurations, etc.). The optical components are combined to produce the beamsplitters. For example, individual prisms (206) and (208) are optical components that can be combined to form a polarization beam splitter (P B S ) (2 1 0). The optical components of the splitting are made prior to the manufacture of the tantalum assembly. The 稜鏡 combination (2 0 1 ) shows four optical components of the splitting, that is, a polarization beam splitter (p B s ) (210), -13 - 1261684, 5^7 j positive 1 imKj 2 1 4 ), and 2 1 6). Each of the polarization beam splitters (hereinafter referred to as PBS) includes a polarization beam splitter film (e.g., 2 15 , 2 1 7 , 2 1 9 , and 2 1 3 ). Preferably, the polarizing beamsplitter films are on the diagonal of the beamsplitters and extend through the corners defined by the outer surface of the pbS. For example, a polarizing beam splitter film (2 1 5 ) along a prism

Since P B S does not have any specific dimensional requirements, optical components having a wide, '' mechanical tolerance can be used. Existing optical component suppliers can mass produce such optical components (and the prisms used to form these components) at a lower cost. These optical components are assembled in a ''outside-to-inside' manner. As shown in Figure 3, each precision alignment angle (300A), (3 00B) ' (3 00C) of an assembly tool (310), and (3 00D ) precisely places the two outer surfaces of each PBS of the four PBSs in the 稜鏡 combination (201) in place.

A tolerance is applied to position the alignment angles and position the alignment angles on the assembly tool base such that the alignment angles accurately fix the outer dimensions of each PBS. Each alignment angle includes a A device that holds the PBS in place during assembly. For example, the PBS (210) is tightly held by vacuum clamps (3 3 0 ) and (335) The alignment angle (300 Α) is connected to the vacuum pump (320) via a vacuum tube (3 2 5 ). In one embodiment, a single vacuum clamp is provided in the corner of the alignment angle. These alignment angles provide the precise dimensional accuracy required to achieve path length matching, and are achieved with mechanical molds, rather than with expensive, tight tolerance optical components. However, the path alone Length matching does not create an acceptable combination of turns. Although the path lengths have been matched, the PBS cannot be accurately assembled because of the inaccurate tolerances (different sizes) of the optical components. (For example, it is not possible to accurately assemble the interleaving plane of PBS (2 1 0 ) and (2 1 4 ), and any dichroic mirror or filter, light sheet placed between the two PBSs), and in the PBS An air gap is created between the inner optical surfaces. The air gap itself causes other problems, including refraction, and other optical changes that need to be mitigated or eliminated.

The optical coupling fluid is usually preferably a refractive index ranging from 1.50 to 1.85. In the experiments conducted by the inventors of the present invention, an optical affinity fluid having a refractive index of 1.6 exhibited good performance. Similarly, in embodiments in which spacers are used, the optical coupling fluid is selected to have a refractive index that preferably matches each of the PBs, optical elements, and spacers as much as possible. The difference in refractive indices between the optical components and the components can be separated to perform the matching of the refractive indices. Another method is to perform an impedance matching type of arithmetic (e.g., to calculate the square root of the sum of the squares of the refractive indices of each optical component/component). However, the inventors of the present invention have noted that the selection of any refractive index between the high refractive index and the low refractive index of the optical components and components provides a ratio of colloidal, hardened epoxy, and other pairs in this paper. Any other embodiment of the combination of path length matching of the air charging embodiment described herein is better matched. It is also possible that the refractive index of each of the matching component interfaces that occurs more frequently in the erbium combination occupies a greater weight in the selected refractive index of the coupled fluid. In one embodiment, the refractive index of the coupling fluid matches the refractive index of the spacers. Important properties to be considered for this coupling fluid are toxicity, flammability, yellowing propensity, chemical properties, and cost. Toxicity and flammability are safety considerations and the product is preferably non-toxic and flammable. In addition, the optically coupled fluid needs to be resistant to yellowing under practical considerations, especially in the presence of strong light and high heat, and is more resistant to yellowing. The optical coupling fluid must have chemical properties that do not react with other optical components, components, and components that are combined with the crucible.

In prior systems, the adhesive required to be able to bond the polycarbonate plastic of the light spinner to the glass of the tantalum assembly. A common solution to this problem is to purchase a "sandwich" form of light polarization rotator from the supplier. In this "sandwich" form, the light rotator has been joined between two cover glass. Such a cover glass makes it easier for the cymbal combination manufacturer to join the light rotator to the iridium combination (eg, to the surface of each adjacent cover glass. However, when compared to the polycarbonate plastic light rotator itself) The light polarization rotator of such a sandwich type has a limited supply source and is relatively expensive. Conversely, in the present invention, the liquid coupling method can directly use a polycarbonate plastic component which is low in cost and easy to obtain. In the case of liquid coupling, the polycarbonate plastic is not bonded to the adhesive, so this type of problem is eliminated. The precise outer dimensions of the tantalum combination obtained using this new manufacturing method are not only directly applicable to such microdisplays. Mounted to the 稜鏡 combination, and precise (or fixed) mounting points can also be used to mount the finished core (with a combination of attached microdisplays) to the device to be used (eg optical engine) ). Due to the use of precise (or fixed) mounting points, the core is reduced or eliminated when the core is mounted to the optical engine. The need for adjustment mechanisms and procedures. Traditional tantalum combinations typically employ a series of glue hardening steps.

幅縮短製造稜鏡組合所需的時間。 本發明包含一種將該等光學元件（例如光學元件 (410)及（420))固定在適當位置之裝置及方法。通常 係將該等光學元件稱爲扁平組件，這是因爲這些光學元件 通常是長方形的且是扁平的（具有較薄的寬度）。然而’ 亦可利用不同形狀及寬度的光學組件來實施本發明。The time required to shorten the manufacturing 稜鏡 combination. The present invention includes an apparatus and method for securing such optical components (e.g., optical components (410) and (420)) in place. These optical components are often referred to as flat components because they are generally rectangular and flat (having a relatively thin width). However, the invention can also be practiced using optical components of different shapes and widths.

Movement toward the central boring hole (70 0 ) may cause the moved component (or parts of the moved component) to move out of the optical path. The present invention provides a method of placing a spacer device in a central sump (700) to maintain the flat components in a substantially stable position. Figure 8 illustrates an example spacer device (800) for securing optical components in position in accordance with an embodiment of the present invention. In the illustrated embodiment, the spacer means (800) is rolled into a tight cylindrical polycarbonate sheet. The spacer device (800) is inserted into the central filling hole (700). Once placed in position, the cylinder will expand π' and press against the components to move the components away from the central boring hole. As described above, a bubble can be left within the stack to cope with the expansion of the components. One problem with component expansion is that these components expand at different ratios. As the optical coupling fluid expands, the optical assembly of the iridium combination also expands. However, the liquid and the optical components expand at different ratios (with different expansions). In most cases of -23-1961 corrected brains, the optically coupled flow system expands at a higher ratio than the optical components. If no air bubbles are present, the expanded liquid or a certain amount of stress is applied to the optical components. If no air bubbles are present, the stress may cause a degree of stress induced damage to the poor birefringence effects of the optical components that pass through the composite when the liquid coupling fluid expands. Referring again to Figure 5, a bubble (550) is shown. Once the filling hole (5 1 0 ) is covered, the bubble (5 5 0 ) is permanently left in the prism assembly. In Figure 5, the "frame" elements (500A, 5 00B, and 5 00C) on the outside of the stack are used to hold the liquid and are used to secure the stack of components. In space. In the embodiment illustrated in Figure 5, the glass, optical elements, and photocoupled liquid of the unitary assembly (e.g., PBs) occupy the volume surrounded by the frame (500) within the stack. As the temperature of the helium combination rises (this will occur during operation), the linear and volumetric dimensions of all components will increase. However, at least in part because the volumetric thermal expansion coefficient of the light-coupled liquid is much higher than the volumetric thermal expansion coefficient of glass and other materials as the temperature rises, the liquid volume expands faster than the glass "container" (optical components and frames that limit the range of liquids) The rate of expansion of the volume. In addition to poor optical effects, the excessive stress induced by such differential expansion has the potential to separate the bonded components. Bubbles (5 5 0 ) are a way to accommodate differential expansion and avoid accumulation stress.

Figure 示出 shows a tube in accordance with an embodiment of the present invention (1 1 〇0 ) In one embodiment of the combination, a tube (1 1 〇〇) is attached to the filling hole (510). A part of the sealing tube (1100) contains a bubble (or air) • 25 - 1261684 Revision year "Supplement 1 (21) (1 1 〇5 ). The bubble (1 1 0 5 ) will be enlarged or reduced to accommodate the liquid in the hydrazine combination (eg, liquid coupling fluid (4 0 0)) expansion or contraction. In this method, similar to the bubble-only method described above, it is important to know the orientation of the prism combination in the application of the optical engine. The reason is · bubble (1 1 〇 5) will move to the highest point within the prism combination. Therefore 'the system must be designed to The end of the closure is a *. The closure can be configured as an elbow or other structure to guide the bubble to a suitable position. In the case of a method in which only bubbles are provided, it is therefore important that The high point of the weir combination (i.e., the high point of the fluid in the weir combination) is not one of the points in the light path of the weir combination.

A sliding piston (12 〇〇) is placed snugly into the tube which is open at both ends. When the light is coupled When the liquid expands as the temperature rises, the piston (1 200 ) slides outward in the tube that is open at both ends. When the light coupling liquid shrinks as the temperature decreases, the surface tension (and/or the inside of the combination) The pressure change from the outside causes the piston to slide inwardly within the open ended tube (1 205). In one embodiment, the length of the open ended tube is greater than a predetermined maximum expanded size of the optically coupled fluid In an alternative embodiment, a stop mechanism is used 1 2 1 0 ) is provided in the tube which is open at both ends so that the piston does not reach the open end of the tube.

每一上述實施例都設有一外框（例如在該稜鏡組合的 光學組件之外的框架（5 00 ))，用以密封該稜鏡組合， 並存放該光學耦合流體（且包含用於前文所述的任何應力 消除功能之任何必要連接機構）。該框架亦將結構強度提 供給該棱鏡組合。然而，本發明亦滿足了對一用來密封光 學耦合流體的小型配置之需求。此種小型配置因而可使該 稜鏡組合被用於更多種的光學應用，其中包括不同的 LCoS型投影系統。Each of the above embodiments is provided with a frame (for example, a frame (500) outside the optical assembly of the cymbal assembly) for sealing the cymbal combination and storing the optical coupling fluid (and for inclusion in the foregoing Any of the necessary connection mechanisms for any of the stress relief functions described). The frame also provides structural strength to the prism assembly. However, the present invention also satisfies the need for a small configuration for sealing optically coupled fluids. This small configuration thus allows the cymbal combination to be used in a wider variety of optical applications, including different LCoS type projection systems.

此外，任何新設計的及（或）先前存在的光學引擎系 統都適合安裝一流體耦合的稜鏡組合。在新的設計中，可 在該投影系統內安裝若干安裝架，以適應一種或多種液態 親合式稜鏡組合的尺寸，而執行液態耦合式稜鏡組合的安 裝。然而，在換裝系統（將液體塡充式稜鏡組合安裝到先 則售出的投影系統，及（或）將液態|禹合式稜鏡組合安裝 到一先則設計的新投影系統）的情形中，可能不是那麼容 易完成液態耦合式稜鏡組合的實體搭載。亦即，一流體耦 合式棱鏡組合的實體尺寸及形狀可能使得該稜鏡組合無法 被直接安裝到一現有光學引擎內爲一傳統棱鏡組合所設的 位置。爲了搭載一流體耦合式稜鏡組合而必須對該光學引 -27-In addition, any newly designed and/or pre-existing optical engine system is suitable for mounting a fluid-coupled combination of turns.

However, in the case of a reloading system (a combination of a liquid-filled cymbal assembly to a previously sold projection system, and/or a liquid-composite cymbal combination to a new projection system designed first) In the middle, it may not be so easy to complete the physical loading of the liquid coupled 稜鏡 combination. That is, the physical size and shape of a fluid-coupled prism assembly may prevent the cymbal assembly from being directly mounted into a position within a conventional optical engine that is provided by a conventional prism assembly.

Thus, the prism assembly can be used as one of any optical engine designs by providing a fluid-coupled cymbal combination that is sealed and provides structural strength and an external dimension similar to an equivalent conventional prism combination. One of the traditional 稜鏡 combinations directly replaces components. The invention disclosed in this document is such a device.

由於這些原因，本案發明人也已經開發出一種密封一 液體塡充式棱鏡組合且將結構整體性提供給該液體塡充式 稜鏡組合之一內部密封式稜鏡組合。For these reasons, the inventors of the present invention have also developed a seal-liquid entangled prism assembly and provide structural integrity to one of the liquid-filled iridium combinations.

The inner sealed jaw assembly (1 300) includes a bottom plate (131 0 ) and at least one inner seal (1 3 20 ) interposed between the optical components of the stack. When comparing this embodiment with the previous configurations, there is no major feature of the external frame other than the base plate (1 3 1 0 ) (the base plate is a combination of a conventional 稜鏡 combined configuration and a fluid affinity 稜鏡Configure a common feature). The bottom plate (131 0 ) provides a stable and solid surface for attaching the PBS (1310 - 1304). As shown in FIG. 13, the inner seal is mounted between the optical elements (410) and (420), mounted with the optical element (410) and the PBS (1302), and mounted on the optical element (420) and the PBS (1303). )between. The inner seal extends a short distance (e.g., 1 mm) from the top of the optical elements/PBS to create a liquid seal for storing the optically coupled fluid that is mounted to the stack. In one embodiment, the inner seal also overlaps the tops of the optical elements (410) and (420) such that the inner cover covers the optical elements -28-1261684 (24): 3⁄4 2. 2? The exposed surface of the dead filler, but preferably does not extend beyond the outer surface of the PBS. In terms of depth, the inner seals ooze between the optical elements/PBS to a returning seal depth (eg, millimeters). Figure 14 is a close-up view (partial view) of an inner seal of an internally sealed prism assembly (1400) in accordance with an embodiment of the present invention. In Fig. 4 [4], two PBSs (1401) and (1402) have an inner seal (e.g., adhesive seal) (1 4 1 0 ) therebetween. The inner seal can be described as a "frame" between the PBS elements. The adhesive does not extend beyond the outer surface of the prism assembly. Preferably, the inner seal is an adhesive which not only seals the jaw combination, prevents leakage of the optical coupling fluid, but also provides additional stiffness to the entire structure. The adhesive may be, for example, a single or double (1 or 2 part) epoxy resin, or a UV hardening adhesive that will harden and seal. In an alternative embodiment, the sealing adhesive may be a soft adhesive such as a silicone adhesive. However, if an uncured sealant is used, the buckling of the tantalum combination may be problematic. Although the bottom plate of the frame provides sufficient rigidity to accept a soft adhesive in some applications, a top plate other than the bottom plate (the side opposite the bottom plate in the file assembly) is added to make the soft adhesive Sufficient stiffness is fully acceptable in almost all applications. Figure 14 also shows an optical element ("planar" optical component (1 4 3 0 )) isolated by each spacer (1 420 ). The optical element is shorter than the bottom of the adhesive sealant. The optical component is a representative, and in fact there may be several optical components, wherein the additional optical spacers are used to isolate and isolate the optical -29-21262684 (25) 丨9^2.2 B correction interface components from the PBS. . The "planar" optical components (1,430) are such as dichroic mirrors, reflective polarizers, and phase difference plates of specific wavelengths disposed between the PBs and suspended in the optical coupling liquid. The planar components are spaced from the glass surfaces by spacer elements as previously described. The penetration of the adhesive (1 4 1 0) (prescribed seal depth) is limited to an area outside the light path. The bottom plate (1 3 1 0 ) provides the required stiffness to the turns combination. As mentioned above, the main advantages of the liquid coupled enthalpy combination technology and configuration disclosed by the present invention include the ability to use low cost, low tolerance glass components, and the ability to produce a 稜鏡 combination with a perfect outer dimension. And when manufacturing the cymbal combination, each microdisplay can be directly attached to the cymbal combination. The advantages of directly attaching the microdisplay to the cymbal combination provide several advantages, the most important of which The advantage is that, under a wide range of conditions, the resulting monolithic combination will remain aligned. An alternative to these advantages is the use of the "outside to inside" process described above. However, at this time, the enthalpy combination is not filled with a light-coupled liquid, but the relevant portion of the combination is made empty and thus "filled" with air. However, in this method, it is necessary to cover all surfaces that are now exposed with an anti-reflective thin film (anti-reflective coating) in order to suppress reflection. No expansion ports are required in this configuration. In some applications, you can also omit the side frame of the frame (for example, 5〇ΟΒ), or you can omit the upper frame (5 00C). In yet another alternative embodiment, the hardened epoxy resin is used to fill the -30-

Preferably, the hardened epoxy resin has a refractive index that is comparable to the refractive indices of the PBs and optical elements used. In yet another embodiment, a colloid can be utilized to fill the junction between adjacent PBSs.

圖 15不出一路徑長度匹配式偏振分光鏡（PBS)立 方體，包括兩個在對角線（1 5 0 0 )上，於層（1 5 1 5 )處成對且 具有第1面（1501)、第2面（ 1 502)及一基準面（ 1 5 03 )的稜 鏡（ 1 5 05)及（15 10)，匹配的路徑長度被顯示爲路徑長度 1(1521)及路徑長度2( 1 522)(其中，路徑長度1=路徑長度 2)。圖 16A示出用來製造一路徑長度匹配式 PBS或分 光立方體的路徑長度匹配裝置（1 6 0 0 )。現在將說明一路 徑長度匹配式 PBS立方體之一製程。Figure 15 shows a path length matched polarizing beam splitter (PBS) cube, consisting of two diagonally (1 500) pairs at the layer (1 5 1 5) and having a first side (1501) ), 第 ( 1 5 05) and (15 10) of the 2nd surface ( 1 502) and a reference plane ( 1 5 03 ), the matching path length is shown as path length 1 (1521) and path length 2 ( 1 522) (where path length 1 = path length 2). Fig. 16A shows a path length matching device (1600) for fabricating a path length matching PBS or a splitting cube. One process of one path length matching PBS cube will now be described.

將路徑長度匹配裝置（1 600 )之組態設定成夾持兩個 稜鏡（例如稜鏡（1610)及（1620))，並提供一精密調 整（例如測微調整裝置（1 63 0 ))，用以對準或匹配通過 這兩個稜鏡的所選擇之路徑長度。將在該製程結束時將構 成一 PBS的這兩個稜鏡（1610)及（1620)定位在該路 徑長度匹配裝置（1 600 )的精密”止動機構”（164〇 )、 (1 65 0 )。使用圖15中定義的術語時，第 ！面（在 上棱鏡（1 6 1 0 ))係沿著面（1 6 4 2 )而貼附到該可調整的 止動機構（1 6 4 0 )，且第 2面（在棱鏡（i 6 2 0 )的側 面）係沿著面（1 6 5 2 )而貼附到該固定的的止動機構 -31 -The configuration of the path length matching device (1 600 ) is set to hold two turns (eg 稜鏡 (1610) and (1620)) and provide a fine adjustment (eg micrometric adjustment device (1 63 0 )) Used to align or match the selected path length through the two turns. The two turns (1610) and (1620) constituting a PBS will be positioned at the end of the process at the precise "stop mechanism" of the path length matching device (1 600) (164〇), (1 65 0 ). When using the term defined in Figure 15, the first! The face (in the upper prism (1 6 1 0 )) is attached to the adjustable stop mechanism (1 6 4 0 ) along the face (1 6 4 2 ), and the second face (at the prism (i 6) The side of the 2 0 ) is attached to the fixed stop mechanism -31 along the face (1 6 5 2 )

1261684 (27) ( 1650)。該固定的止動機構（1650)，舉例來說，爲一固 定的真空保持止動機構。1261684 (27) (1650). The fixed stop mechanism (1650) is, for example, a fixed vacuum retention stop mechanism.

穩固但暫時性地將該等稜鏡貼附到該等止動機構的一 種方法即是使用一真空保持裝置。例如，係將一真空吸盤 (圖中未示出）置於每一止動機構上的至少一個位置，且 連接到真空吸盤的一真空線提供用來將該等稜鏡固定在定 位之吸力。然而，亦可使用諸如夾鉗等的其他裝置。因 此，係將該等稜鏡置於該路徑長度匹配裝置的對應的止動 機構中之位置上。One method of attaching the crucibles to the arresting mechanisms in a stable but temporary manner is to use a vacuum holding device. For example, a vacuum chuck (not shown) is placed in at least one position on each stop mechanism, and a vacuum line connected to the vacuum chuck provides suction for securing the jaws in position. However, other devices such as clamps can also be used. Therefore, the turns are placed in positions in the corresponding stop mechanisms of the path length matching device.

施加一黏著劑（例如一紫外線硬化黏著劑），以便塡 滿上稜鏡與下稜鏡間之間隙。每一止動機構的面上設有一 精確定位的對準目標。該對準目標是一條細線（約爲 10 微米）。止動機構（1640)包含對準目標（16 44 )，且止 動機構（ 1650)包含對準目標（ 1654)。一高解析的攝錄 機（1 6 7 1 )經由稜鏡（1 6 1 0 )的一基準面（1 6 1 2 )而”檢查 ”尙未裝配的 PBS。經由該攝錄機觀測兩條對準線。當 這兩條對準線重疊時，即完成了路徑長度匹配。沿著上稜 鏡（1610)與下稜鏡（1 620 )間之對角線（1 660 ) ”滑動 ”該上棱鏡，即可使這兩條線重疊。 目視觀測該稜鏡組合，並調整該稜鏡組合，而執行調 整的量。憑著經驗，裝配人員將可估計一調整量，並將該 調整量輸入該測微計，然後或許進行一次或兩次較小的調 整，以便將該等棱鏡定位到一路徑長度匹配的位置。然 而，輸入到該測微計的一精確數字之知識不是不可或缺 -32-Apply an adhesive (such as an ultraviolet curing adhesive) to fill the gap between the upper and lower jaws. A precisely positioned alignment target is provided on the face of each stop mechanism. The alignment target is a thin line (approximately 10 microns). The stop mechanism (1640) includes an alignment target (16 44 ) and the stop mechanism ( 1650 ) includes an alignment target ( 1654). A high resolution camcorder (1 6 7 1) "checks" the unassembled PBS via a reference plane (1 6 1 2 ) of 稜鏡 (1 6 1 0). Two alignment lines are observed through the camcorder. When the two alignment lines overlap, the path length matching is completed. The upper prism is slid along the diagonal line (1 660 ) between the upper prism (1610) and the lower jaw (1 620 ) to overlap the two lines. Visually observe the sputum combination and adjust the sputum combination to perform the adjustment. Based on experience, the assembler will be able to estimate an adjustment and enter the adjustment into the micrometer, and then perhaps make one or two minor adjustments to position the prisms to a path length match. However, knowledge of an exact number entered into the micrometer is not indispensable -32-

1261684 (28) 的’且只要耢由觀測及調整之方式即可達到路徑長度匹配 的位置。因此，可以精密調整螺絲或可被配置成沿著這兩 個棱鏡的對角線而移動這兩個稜鏡的相對位置之任何裝置 來取代測微計（1 6 3 0 )。1261684 (28) 'and as long as the path length is matched by observation and adjustment. Thus, the micrometer (1 6 3 0 ) can be replaced by a fine adjustment screw or any device that can be configured to move the relative positions of the two turns along the diagonal of the two prisms.

此外’請注意，係沿著該等棱鏡的對角線滑動該等稜 鏡，而精細地進行路徑長度調整，而且因爲該等稜鏡通常 並未正好具有相同的尺寸，所以該等稜鏡角將不會完全地 對準（在對角線的每一末端向下觀察）。在該完成路徑長 度匹配的分光鏡（例如PBS)中，突出的量與該等稜鏡 尺寸的不均一（或不相同）的量成正比。在採用具有相同 尺寸的均一稜鏡時，將可平坦地將該等稜鏡匹配在一起， 然而如前文所述，稜鏡建構時的此種精密度是成本極高 的。因此’本發明可在無須精密尺寸的稜鏡之情形下進行 路徑長度匹配的建構。In addition, 'note that the 稜鏡 is slid along the diagonal of the prisms, and the path length is finely adjusted, and because the cymbals usually do not have exactly the same size, the horns are Will not be fully aligned (observed down at each end of the diagonal). In the beam splitter (e.g., PBS) that completes the path length matching, the amount of protrusion is proportional to the amount of non-uniformity (or different) of the size of the pupils. When uniform enthalpy of the same size is used, the enthalpy will be flattened together, however, as described above, such precision in 稜鏡 construction is extremely costly. Therefore, the present invention can perform path length matching construction without the need for a precision-sized crucible.

在圖 1 6 A 所示之實施例中，係利用一測微計 (1 63 0 )來調整上稜鏡的位置，並使該等對準線重疊。在 一實施例中’一操作人員在一顯示螢幕上監視攝錄機的輸 出，並以手動方式轉動該測微計的調整裝置，直到該等對 準目標重疊爲止。在另一實施例中，該攝錄機係連接到一 具有視覺系統軟體的運算裝置，而該軟體將辨識出已對準 該等對準目標之時機。電腦產生的信號將通知一操作人員 要如何調整該測微計，或者係以一由該視覺系統控制的一 步進馬達（或其他控制馬達）來調整該測微計。在另一實 施例中’係以一目鏡取代該攝錄機，且該操作人員以該目 - 33-In the embodiment shown in Fig. 16A, a micrometer (1 63 0 ) is used to adjust the position of the upper jaw and to overlap the alignment lines. In one embodiment, an operator monitors the output of the camcorder on a display screen and manually rotates the adjustment device of the micrometer until the alignment targets overlap. In another embodiment, the camcorder is coupled to an arithmetic device having a vision system software that will recognize the timing at which the alignment targets are aligned. The computer generated signal will inform an operator how to adjust the micrometer or adjust the micrometer with a stepper motor (or other control motor) controlled by the vision system. In another embodiment, the camcorder is replaced by an eyepiece, and the operator takes the item - 33-

最後，一旦滿意了該對準之後，利用一紫外線燈照射 該 P B S，以便使黏著劑硬化，並將該等組件鎖定於定 位。圖 16B 中示出使用圖 16A所示之裝置來製造一路 徑長度匹配的分光鏡之一完整製程。爲了製造一偏振分光 鏡（P B S )，要增加一道將一偏振層薄膜施加到其中一個 該等稜鏡的一對角線或每一該等稜鏡對角線之間的額外步 驟。增加或替換一不同的薄膜，即可建構出其他類型的分 光鏡（例如增加了一彩色層的彩色分光鏡）。Finally, once the alignment is satisfied, the P B S is illuminated with an ultraviolet lamp to harden the adhesive and lock the components in position. A complete process for fabricating a path length matched beam splitter using the apparatus of Fig. 16A is illustrated in Fig. 16B. In order to fabricate a polarizing beam splitter (P B S ), an additional step of applying a polarizing layer film to a pair of corners of one of the turns or between each of the diagonals is added. Other types of beamsplitters can be constructed by adding or replacing a different film (e.g., a color beam splitter with a colored layer added).

現在將說明製造一路徑長度匹配的 PB S立方體之一 第二方法。價 1 7示出用來製造根據本發明另一實施例 的一路徑長度匹配的 PBS 立方體之一裝置。圖 17所 示裝置的數項特徵與圖 16A所示之裝置相同。將構成該 PBS 的兩個稜鏡係被夾持到精密止動機構（1 640 )及 (1 65 0 )。第 1面（在上稜鏡（1610 )上）係貼附到可 調整的止動機構（1 640 )，且第 2 面（在下稜鏡 (1 620 )上）係貼附到固定的止動機構（1 65 0 )。仍然利 用一真空保持裝置將該等稜鏡穩固地但暫時性地貼附到該 等止動機構。如前文所述，施加一黏著劑（最好是一紫外 線硬化黏著劑），以便沿著對角線（1 660 )而塡滿該上稜 鏡與下稜鏡間之間隙。 係將一對準目標置於每一止動機構的面上。在該實施 例中，該對準目標的位置無須精確。一高解析的攝錄機經 -34-A second method of fabricating a path length matched PB S cube will now be described. Price 17 shows one of the devices used to fabricate a path length matching PBS cube in accordance with another embodiment of the present invention. The several features of the device shown in Fig. 17 are the same as those of the device shown in Fig. 16A. The two tethers constituting the PBS are clamped to the precision stop mechanism (1 640 ) and (1 65 0 ). The first face (on the upper jaw (1610)) is attached to the adjustable stop mechanism (1 640), and the second face (on the lower jaw (1 620)) is attached to the fixed stop. Institution (1 65 0 ). These cymbals are still firmly or temporarily attached to the stop mechanisms using a vacuum retaining device. As previously described, an adhesive (preferably an ultraviolet hardening adhesive) is applied to fill the gap between the upper prism and the lower jaw along the diagonal (1 660).

In this embodiment, the depth of field of the camcorder (Depth Of Filed; The choice of DOF) (determined by the lens (16 7 2)) is very limited (narrow depth of field). The micrometer (1 6 3 0) adjusts the position of the upper jaw until the camcorder sees both Aligning the targets while aiming at the same focus. When the two alignment targets are in focus, the same distance is obtained from the two alignment targets to the reference plane (and the focal plane of the camcorder) (matching Path length). The D0F of the camcorder receives a limit, so that it can only be configured in a path length matching position within a tolerance range required to use a product of the PB S. The alignment targets are simultaneously aimed at the focus. As described above, when the alignment is satisfied, the final step is to irradiate the PBS with an ultraviolet lamp and harden the adhesive.

Figure 6 shows no other configuration and core configuration (6 800).

仍然請注意，該等圖式只示出該組態的光學部分。實 際的稜鏡可能需要額外的組件。例如，可將一 ’，清理’， 偏光板***輸入PBS (6710)，以便改善反差比。該偏 光板最好是一反射型偏光板。此外，可將，，玻璃間隔物’， ***任何P B S之間，以便使自該等微型顯示器的反射表 面至輸出PBS的輸出面之光路徑長度相同。如同本文所 述的任何核心組態，可採用液態耦合及（或）精密對準角 (例如，請參閱圖3及5 )，且該等 P B S可以是路徑 長度匹配的 P B S裝置（例如，類似於圖15所示的且 根據圖 16A、16B、及 17 中之任一圖所建構的 PBS 裝置）。Still please note that these figures only show the optical part of the configuration. The actual flaws may require additional components. For example, a 'cleaning', polarizing plate can be inserted into the input PBS (6710) to improve the contrast ratio. The polarizing plate is preferably a reflective polarizing plate. In addition, glass spacers can be inserted between any P B S so that the optical path lengths from the reflective surface of the microdisplays to the output face of the output PBS are the same. As with any of the core configurations described herein, liquid coupling and/or precision alignment angles can be employed (see, for example, Figures 3 and 5), and the PBSs can be path length matched PBS devices (e.g., similar) The PBS device shown in Fig. 15 and constructed in accordance with any of Figs. 16A, 16B, and 17).

採用液態接合區的一個優點在於：此種耦合方式的效 率筒出§午多（例如較少的反射）。另一個優點是：藉由取 消了玻璃間隔物’並調整液態接合區的厚度，而有可能減 少組件數。此外，在光路徑中的該等組件間之”接合區” 可以是傳統的方式，亦即爲一堅硬的黏著劑。 稜鏡及核心組態都可使用的一額外組態替代方式是以 方位爲 4 5度的一反射式偏光板取代一個或多個 p b S。 (目前係由 M oxtek股份有限公司製造此種反射式偏光 板）。 -40-One advantage of using a liquid junction zone is that the efficiency of this coupling mode is more than a midday (e.g., less reflection). Another advantage is that it is possible to reduce the number of components by eliminating the glass spacers and adjusting the thickness of the liquid junction. Moreover, the "junction zone" between the components in the light path can be a conventional manner, i.e., a hard adhesive. An additional configuration alternative that can be used with the core configuration is to replace one or more p b S with a reflective polarizer with an orientation of 45 degrees.

In some projector applications, such as screens containing a linear polarizer, all of the light output from the chirp is preferably linearly polarized in one direction. This can be achieved by placing a magenta/green color optic phase-selective plate in series with the output beam. Figure 69 illustrates a stack and core configuration (6900) in accordance with an embodiment of the present invention. Each optical component of the core configuration has a name and the path and polarization of the light at each point within the combination are indicated. Note that the partial silver-plated lens (69 1 0) can be adjusted to split the input unpolarized light (input (6905)) to match the light and 稜鏡 output from the light source (and/or other in the entire light management system) The characteristics of the component and the eye response of the viewer. For example, you can choose 値 as 1/3 and 2/3. Also note that in order to simplify the drawing, the intensity of the beam is omitted at all points in the figure. Please note that Figure 69 shows only the optical portion of the configuration. The actual combination of 可能 may require additional components. More specifically, for example, a quarter-wave plate can be inserted after any P B S or two P B S to provide skewed light compensation. In addition, a number of "glass spacers" may be inserted as needed to provide the same optical path length from the reflective surface of the microdisplays to the output of the composite. Still liquid between components in the optical path may be employed. Coupling the liquid junction zone") or a conventional hard adhesive. Another advantage of using a liquid junction is that the number of components can be reduced by eliminating the glass spacer and adjusting the thickness of the liquid junction. -41 -
