Description
本發明有關於一種光學裝置。更特定而言，本發明揭示一種用於高解析度表面成像之透鏡陣列。The invention relates to an optical device. More particularly, the present invention discloses a lens array for high resolution surface imaging.
在傳統上，此用於一對一影像光學掃瞄器之透鏡為一種桿透鏡陣列。請參考第1圖，其為習知技術桿透鏡陣列100之透視圖。此桿透鏡陣列100是由複數個纖維光學桿透鏡110所建構。各個別纖維光學桿透鏡110是由一纖維光學玻璃束(strand)切割而成，且其終端必須被拋光。然後，將複數個纖維光學桿透鏡110在一框(frame)120中側靠側地以其光軸平行而配置成一列或多個列，且藉由一黏著層130而保持定位。此等纖維光學桿透鏡110典型地是由分等級折射率(GRIN)纖維所製成，其所具有玻璃之折射率在製造期間被小心控制、而具有從中心軸至邊緣而徑向減少之分等級折射率。Traditionally, this lens for a one-to-one image optical scanner is a rod lens array. Please refer to FIG. 1, which is a perspective view of a prior art rod lens array 100. The rod lens array 100 is constructed from a plurality of fiber optic rod lenses 110. Each individual fiber optic rod lens 110 is cut from a fiber optic glass strand and its ends must be polished. Then, the plurality of fiber optic rod lenses 110 are arranged side by side in a frame 120 with their optical axes paralleled in one or more columns, and are held in position by an adhesive layer 130. These fiber optic rod lenses 110 are typically made of graded index (GRIN) fibers having a refractive index that is carefully controlled during manufacturing and has a radial reduction from the central axis to the edges. Grade index of refraction.
然而，此種型式透鏡製造昂貴。GRIN型式纖維光學玻璃束之昂貴是由於其本身之原因：將此等束切割且拋光至準確長度，以形成纖維光學桿透鏡110；將此等纖維光學桿透鏡110組裝於框120中，以致於其軸準確地平行；以及將此等纖維光學桿透鏡110黏在一起。此等均為須要精準之步驟，其整個技術仍必須發展以滿足其要求。However, this type of lens is expensive to manufacture. The GRIN type fiber optic glass bundle is expensive for its own sake: the bundles are cut and polished to an exact length to form the fiber optic rod lens 110; the fiber optic rod lenses 110 are assembled in the frame 120 such that The axes are exactly parallel; and the fiber optic rod lenses 110 are bonded together. These are all steps that require precision and the entire technology must still evolve to meet their requirements.
此外，此種型式透鏡之主要缺點為：由於透鏡之數目與難以將其配向，以致於並不實際形成此等透鏡之終端，以致於其可以放大其用於成像之表面；因而使用平坦之終端。為了增加成像解析度，必須使用較大數目之較小直徑之桿透鏡110，此在當所想要之解析度增加時，會限制最大解析度且提高成本。此外，此用於所須GRIN纖維光學束之供應商有限，且因此基本材料本身為昂貴。Moreover, the main disadvantage of such a type of lens is that the number of lenses is difficult to align with them, so that the terminals of such lenses are not actually formed, so that they can magnify the surface for imaging; thus using a flat terminal . In order to increase the imaging resolution, a larger number of smaller diameter rod lenses 110 must be used, which limits maximum resolution and increases cost as the desired resolution increases. Moreover, this supplier for the required GRIN fiber optic bundle is limited, and thus the base material itself is expensive.
此外，此使用於傳統桿透鏡中之玻璃包含鉛，其對於環境並不有善。In addition, the glass used in the conventional rod lens contains lead, which is not good for the environment.
因此，須要一種改良式透鏡陣列，其材料實質上較便宜，且其較簡單製造，且其可以增加解析度而無須實質上增加成本。Accordingly, there is a need for an improved lens array that is substantially less expensive in material and that is relatively simple to manufacture and that can increase resolution without substantially increasing cost.
為了達成根據本發明目的之此等與其他優點，且以便克服傳統方法之缺點、其如同在此實現且廣泛說明者，本發明提供一種透鏡陣列，其複數個透鏡面被模製成聚合物條之表面，因此使用較便宜材料而簡化製造過程，且可將此等透配向而無須大量製造基礎結構。In order to achieve this and other advantages in accordance with the purpose of the present invention, and to overcome the disadvantages of conventional methods, as embodied and broadly described herein, the present invention provides a lens array in which a plurality of lens faces are molded into polymer strips The surface, therefore, simplifies the manufacturing process using less expensive materials, and can be aligned without the need to extensively fabricate the infrastructure.
本發明更提供一種透鏡陣列，其透鏡面在設計時可被組態，以支持所增加之解析度。The present invention further provides a lens array whose lens face can be configured at design time to support the increased resolution.
本發明之透鏡陣列包括：兩個相同之蓋、兩個相同之透鏡區段、以及一個中間維持件。各透鏡區段包括：設置在透鏡區段頂與底上之複數個透鏡。此透鏡陣列以設置在兩個透鏡區段間之中間維持件而組裝。設置此兩個蓋，以致於一個蓋是在此上透鏡區段之頂上，且另一個蓋設置在此下透鏡區段之底上。此兩個蓋將此透鏡陣列組裝保持在一起。The lens array of the present invention comprises: two identical covers, two identical lens segments, and an intermediate support. Each lens segment includes a plurality of lenses disposed on the top and bottom of the lens segment. This lens array is assembled with an intermediate holder disposed between the two lens segments. The two covers are arranged such that one cover is on top of the upper lens section and the other cover is placed on the bottom of the lower lens section. These two covers hold the lens array assembly together.
由於各透鏡區段相同，且各蓋相同，可以將相同透鏡區段之工具使用於所有透鏡區段，且可以將相同蓋之工具使用於所有蓋。因此，可以降低製造成本且簡化組裝。Since the lens segments are the same and the covers are the same, the same lens segment tool can be used for all lens segments, and the same cover tool can be used for all the covers. Therefore, the manufacturing cost can be reduced and the assembly can be simplified.
複數個第一透鏡收集由一物件所反射光線且將其聚焦，以致於此光線以擴散光束經由第一透鏡區段而行進至複數個第二透鏡之表面。此光線是由外部來源產生。此中間維持件阻擋且吸收散射光線，而複數個孔允許所想要經聚焦光線抵達複數個第三透鏡之表面。此光線然後通過第二透鏡區段，且經由複數個第四透鏡之表面射出，此等複數個第四透鏡將此光線聚焦於一或多個感測器上。A plurality of first lenses collect and focus the light reflected by an object such that the light travels through the first lens section to the surface of the plurality of second lenses. This light is produced by an external source. The intermediate support blocks and absorbs scattered light, while the plurality of apertures allow the desired focused light to reach the surface of the plurality of third lenses. The light then passes through the second lens segment and exits through the surface of the plurality of fourth lenses, which focus the light onto one or more sensors.

參考第8圖，其說明根據本發明一實施例之經由透鏡陣列之透鏡區段之成像。Referring to Figure 8, an illustration of imaging through a lens segment of a lens array in accordance with an embodiment of the present invention is illustrated.
在應用中，此物件設置在一位置、其提供在透鏡陣列之透鏡區段220上之適當焦點。光線照射此物件之區域。例如將此等區域指定為A與A’。當光線照射物件A與A’時，且此光線經由透鏡223A進入頂透鏡區段220A。此光線行經經由頂透鏡區段220A，且經由透鏡224A射出。此光線繼續經由兩個透鏡區段間之空間，且經由透鏡224B而進入底透鏡區段220B。此光線行進經由底透鏡區段220B，且經由透鏡223B射出。此透鏡導引光線，以致於將物件A與A’之影像聚焦，且獲得物件之適當影像。例如，將此光線導引朝向偵測且儲存影像資料之感測器陣列。In use, the article is placed in a position that provides the appropriate focus on the lens section 220 of the lens array. Light illuminates the area of the object. For example, these areas are designated as A and A'. When the light illuminates the objects A and A', and the light enters the top lens section 220A via the lens 223A. This light travels through the top lens section 220A and exits through lens 224A. This light continues through the space between the two lens segments and enters the bottom lens segment 220B via lens 224B. This light travels through the bottom lens section 220B and exits through the lens 223B. The lens directs light so that the images of objects A and A' are focused and an appropriate image of the object is obtained. For example, the light is directed toward a sensor array that detects and stores the image data.
參考第9A圖，其說明根據本發明一實施例之經由具有焦點中物件之透鏡陣列之透鏡區段之成像；參考第9B圖，其說明根據本發明一實施例之經由具有在焦點平面上1mm物件之透鏡陣列之透鏡區段之成像；以及參考第10圖，其說明根據本發明一實施例之透鏡陣列之經由焦距之表現。Referring to FIG. 9A, an illustration of a lens segment via a lens array having an object in focus is illustrated in accordance with an embodiment of the present invention; and FIG. 9B illustrates a via 1 mm on a focal plane in accordance with an embodiment of the present invention. Imaging of the lens segments of the lens array of objects; and reference to Figure 10, which illustrates the performance of the lens array via focal length in accordance with an embodiment of the present invention.
如同於第9A、9B、以及10圖中所顯示，本發明之透鏡陣列提供優異之性能表現。即使此物件偏離理想焦點位置1mm，而可以獲得可接受影像。本發明之透鏡陣列提供改良之視域深度。此外，此透鏡陣列具有加強之影像均勻度與亮度。As shown in Figures 9A, 9B, and 10, the lens array of the present invention provides excellent performance. Even if the object is 1 mm away from the ideal focus position, an acceptable image can be obtained. The lens array of the present invention provides an improved depth of field. In addition, the lens array has enhanced image uniformity and brightness.
在一實施例中，此第一透鏡區段與第二透鏡區段是由折射實質上透明聚合物製成，以及蓋與中間維持件是由不透明黑聚合物所製成，以吸收及/或阻擋不想要之散射或外部光線。In one embodiment, the first lens segment and the second lens segment are made of a refractive substantially transparent polymer, and the cover and intermediate support are made of an opaque black polymer to absorb and/or Block unwanted scattering or external light.
當使用此透鏡陣列組裝於一影像掃瞄器中時，非常重要的是，此影像光線並不由一透鏡進入並不與其垂直之另一透鏡中。當此光線進入相鄰透鏡中時，此感測器所擷取之所產生影像為相鄰透鏡之幻像影像。When using this lens array for assembly in an image scanner, it is very important that the image light is not entered by a lens and is not perpendicular to the other lens. When the light enters the adjacent lens, the image captured by the sensor is a phantom image of the adjacent lens.
本發明之一優點為，由於中間維持件之壁厚度延伸至個別透鏡之邊緣，而可以避免串擾。One advantage of the present invention is that crosstalk can be avoided because the wall thickness of the intermediate support extends to the edges of the individual lenses.
如果此透鏡陣列組裝並不具有適當透鏡殼體，光線可以通過透鏡之間且造成幻影。然而，在本發明中，如果光線由一透鏡進入中間維持件之中間圓孔中，此光線由此中間維持件之壁所吸收，因而防止不想要之光線進入相鄰透鏡。因此，可以去除串擾且防止幻影。If this lens array assembly does not have a suitable lens housing, light can pass between the lenses and cause phantoms. However, in the present invention, if light enters the intermediate circular hole of the intermediate maintaining member by a lens, the light is absorbed by the wall of the intermediate maintaining member, thereby preventing unwanted light from entering the adjacent lens. Therefore, crosstalk can be removed and phantoms can be prevented.
此透鏡陣列之每英吋點(DPI)解析度可以在設計時、藉由改變此四透鏡組之光學半徑、圓錐常數、或非球形係數而調整。與此習知技術桿透鏡相對，可以設計此透鏡陣列將此成像之表面放大。The resolution per inch (DPI) of the lens array can be adjusted at design time by changing the optical radius, conic constant, or asphericity of the four lens group. In contrast to this prior art rod lens, this lens array can be designed to magnify this imaged surface.
此透鏡陣列藉由降低製造複雜度與材料成本，而提供優於習知技術之實質改良。此外，此透鏡陣列使得此使用透鏡陣列之裝置相較於習知技術實質上較容易增加此裝置之解析度。This lens array provides a substantial improvement over conventional techniques by reducing manufacturing complexity and material cost. Moreover, this lens array makes such a device using a lens array substantially easier to increase the resolution of the device than conventional techniques.
