Definitions
- the present invention relates to substrate-guided optical devices, and particularly to devices which include a plurality of reflecting surfaces carried by a common light-transmissive substrate, also referred to as a light-guide.
- the invention can be implemented to advantage in a large number of imaging applications, such as, for example, head-mounted and head-up displays (HMD's and HUD's), cellular phones, compact displays, 3-D displays, compact beam expanders, as well as non-imaging applications such as flat-panel indicators, compact illuminators and scanners.
- imaging applications such as, for example, head-mounted and head-up displays (HMD's and HUD's), cellular phones, compact displays, 3-D displays, compact beam expanders, as well as non-imaging applications such as flat-panel indicators, compact illuminators and scanners.
- an optical module serves both as an imaging lens and a combiner, in which a two-dimensional display is imaged to infinity and reflected into the eye of an observer.
- the display can be obtained directly from either a spatial light modulator (SLM) such as a cathode ray tube (CRT), a liquid crystal display (LCD), an organic light emitting diode array (OLED), or a scanning source and similar devices, or indirectly, by means of a relay lens or an optical fiber bundle.
- SLM spatial light modulator
- CTR cathode ray tube
- LCD liquid crystal display
- OLED organic light emitting diode array
- the display comprises an array of elements (pixels) imaged to infinity, by a collimating lens and transmitted into the eye of the viewer by means of a reflecting or partially reflecting surface acting as a combiner for non-see-through and see-through applications, respectively.
- a conventional, free-space optical module is used for these purposes.
- FOV field-of-view
- the strive for compactness has led to several different complex optical solutions, all of which, on the one hand, are still not sufficiently compact for most practical applications, and, on the other hand, suffer major drawbacks in terms of manufacturability.
- the eye-motion-box (EMB) of the optical viewing angles resulting from these designs is usually very small - typically less than 8 mm.
- EMB eye-motion-box
- the performance of the optical system is very sensitive, even to small movements of the optical system relative to the eye of the viewer, and does not allo sufficient pupil motion for conveniently reading text from such displays. Disclosure of the Invention
- the present invention facilitates the structure and fabrication of very compact light-guide optical elements (LOE) for, amongst other applications, head-mounted displays.
- the invention allows relatively wide FOV's together with relatively large EMB values.
- the resulting optical system offers a large, high-quality image, which also accommodates large movements of the eye.
- the optical system offered by the present invention is particularly advantageous because it is substantially more compact than state-of-the-art implementations and yet it can be readily incorporated, even into optical systems having specialized configurations.
- the invention also enables the construction of improved HUD's.
- HUD's have become popular and they now play an important role,, not only in most modern combat aircrafts, but also in civilian aircrafts, in which HUD systems have become a key component for low-visibility landing operation.
- All HUD's of the current designs require a display source that must be offset a significant distance from the combiner to ensure that the source illuminates the entire combiner surface.
- the combiner-projector HUD system is necessarily bulky and large, and requires considerable installation space, making it inconvenient for installation and, at times, even unsafe to use.
- the large optical aperture of conventional HUDs also pose a significant optical design challenge, rendering the HUD's with either a compromising performance, or leading to high cost wherever high-performance is required.
- the chromatic dispersion of high-quality holographic HUD's is of particular concern.
- An important application of the present invention relates to its implementation in a compact HUD, which alleviates the aforementioned drawbacks.
- the combiner is illuminated with a compact display source that can be attached to the substrate.
- the overall system is very compact and can readily be installed in a variety of configurations for a wide range of applications.
- the chromatic dispersion of the display is negligible and, as such, can operate with wide spectral sources, including a conventional white-light source.
- the present invention expands the image so that the active area of the combiner can be much larger than the area that is actually illuminated by the light source.
- a further application of the present invention is to provide a compact display with a wide FOV for mobile, hand-held application such as cellular phones. In today's wireless Internet-access market, sufficient bandwidth is available for full video transmission.
- the limiting factor remains the quality of the display within the end-user's device.
- the mobility requirement restricts the physical size of the displays, and the result is a direct-display with a poor image viewing quality.
- the present invention enables, a physically very compact display with a very large virtual image. This is a key feature in mobile communications, and especially for mobile Internet access, solving one of the main limitations for its practical implementation. Thereby, the present invention enables the viewing of the digital content of a full format Internet page within a small, hand-held device, such as a cellular phone.
- a broad object of the present invention therefore, is to alleviate the drawbacks of state-of-the-art compact optical display devices and to provide other optical components and systems having improved performance, according to specific requirements.
- the invention therefore provides an optical device, comprising a , light- transmitting substrate having at least two major surfaces parallel to each other and edges; optical means for coupling light waves located in a field-of-view into said substrate by internal reflection, and at least one partially reflecting surface located in said substrate which is non-parallel to said major surfaces of the substrate, characterized in that at least one of said major surfaces is coated with a dichroic coating.

- Fig. 10 illustrates an exemplary HUD system in accordance with the present invention
- Fig. 1 illustrates a conventional folding optics arrangement, wherein the substrate 2 is illuminated by a display source 4.
- the display is collimated by a collimating lens 6.
- the light from the display source 4 is coupled into substrate 2 by a first reflecting surface 8, in such a way that the main ray 10 is parallel to the substrate plane.
- a second reflecting surface 12 couples the light out of the substrate and into the eye of a viewer 14.
- v is the refractive index of the substrate.
- the refractive index values lie in the range of 1.5-1.6.
- the diameter of the eye pupil is 2-6 mm.
- the distance between the optical axis of the eye and the side of the head, / is, typically, between 40 and 80 mm. Consequently, even for a small FOV of 8°, the desired substrate thickness would be of the order of 12 mm.
- the system thickness remains limited by a similar value.
- the FOV is limited by the diameter of the projection of the reflective surface 12 on the substrate plane.
- the maximum achievable FOV due to this limitation, is expressed as:
- a sur is the angle between the reflecting surface and the normal to the substrate plane
- R eye is the distance between the eye of the viewer and the substrate (typically, about 30-40 mm).
- Practically tan ⁇ ,. cannot be much larger than 1 ; hence, for the same parameters described above for a FOV of 8°, the required substrate thickness here is on the order of 7 mm, which is an improvement on the previous limit. Nevertheless, as the desired FOV is increased, the substrate thickness increases rapidly. For instance, for desired FOVs of 15° and 30° the substrate limiting thickness is 18 mm or 25 mm, respectively.
- the present invention utilizes an array of selectively reflecting surfaces, fabricated within a LOE. Fig.
- the first reflecting surface 16 is illuminated by a collimated input plane wave 18, emanating from a display light source (not shown) located behind the device, wherein the plane wave 18 is one of a set of light waves located within a given FOV to be coupled into the LOE.
- the reflecting surface 16 reflects the incident light from the source such that the light is trapped inside a planar substrate 20 by total internal reflection. After several reflections off the surfaces of the substrate, the trapped wave reaches an array of selectively reflecting surfaces 22, which couple the light wave 23 out of the substrate into the EMB 24 of a viewer.
- the output light wave 23 should be a plane wave, otherwise, different rays representing a single point at the display source will arrive at the EMB 24 of the viewer at different incident angles and ghost images that interfere with the primary image will be seen by the viewer.
- the output light wave 23, and hence the input wave 18, should be plane waves. That is, the angular deviation between two different rays located on the same light wave should be less than a res , wherein a res is the angular resolution of the optical device.
- a res is ⁇ 1-2 milliradians, but different devices can yield different angular resolutions.
- the angle ⁇ sur2 between the reflecting surfaces and the substrate plane is: a * (4) a sur2 ⁇ ' 2
- the trapped rays arrive at the reflecting surfaces from two distinct directions 28, 30.
- the trapped rays arrive at the reflecting surface from one of these directions 28 after an even number of reflections from the substrate surfaces 26, wherein the incident angle ⁇ ref between the trapped ray and the normal to the reflecting surface is: '-' ⁇ in ( 5 ) ⁇ , ref a in &sur2 ⁇ 2
- the reflectance for one of these two directions should be negligible.
- FIG. 3 A and 3B illustrate the desired reflectance behavior of selectively reflecting surfaces. While the ray 32 (Fig. 3A), having an off-axis angle of ⁇ r ⁇ ?/ — 25°, is partially reflected and is coupled out of the substrate 34, the ray 36 (Fig..3B), which arrives at an off-axis angle of ⁇ % e ⁇ 75° to the reflecting surface (which is equivalent to ⁇ V e / ⁇ 105°), is transmitted through the reflecting surface 34 without any notable reflection. Figs.
- FIG. 4 and 5 show the reflectance curves of a dichroic coating designed to achieve the above reflectance characteristics, for four different incident angles: 20°, 25°, 30° and 75°, with P-polarized and S-polarized light respectively. While the reflectance of the high-angle ray is negligible over the entire relevant spectrum, the rays at off-axis angles of 20°, 25° and 30°, obtain almost constant reflectance of 26%, 29% and 32% respectively, for P-polarized light, and 32%, 28% and 25% respectively, for S-polarized light, over the same spectrum. Evidently, reflectance decreases with the obliquity of the incident rays for P-polarized light and increases for S-polarized light. Fig.
- the LOE only for the P-polarized light. This would be satisfactory for a system using a polarized display source, such as an LCD, or for a system where the output brightness is not crucial and the S-polarized light can be filtered out.
- a polarized display source such as an LCD
- S-polarized light cannot be neglected and it must be taken into account during the design procedure.
- the projection of a reflection surface 22 on the substrate plane is S 2 - T tan( ⁇ sur2 ).
- the projection of each surface is adjacent to its neighbor.
- the embodiment described above with regard to Fig. 7 is an example of a method for coupling the input waves into the substrate.
- Input waves could, however, also be coupled into the substrate by other optical means, including, but not limited to, folding prisms, fiber optic bundles, diffraction gratings, and other solutions.
- the input waves and the image waves are located on the same side of the substrate. Other configurations are envisioned in which the input and the image waves could be located on opposite sides of the substrate.
- Fig. 7 is a detailed sectional view of an array of selectively reflective surfaces which couple light, trapped inside the substrate, out and into the eye of a viewer.
- the maximal FOV is: 2Tt a surl - d eye (9) FOV ⁇ * R eye
- the limiting substrate thickness for an FOV of 8° is in the order of 2.8 mm; for FOVs of 15° and 30°, the limiting substrate thickness is 3.7 mm and 5.6 mm, respectively.
- FOVs of 15° and 30° are more favorable values than the limiting thickness of the state-of-the-art solutions discussed above.
- more than two selectively reflecting surfaces can be used.
- the limiting substrate thickness for FOVs of 15° and 30° is approximately 2.4 mm and 3.9 mm, respectively.
- additional reflecting surfaces may be introduces to, amongst other advantages, reduce the limiting optical thickness further. For configuration where a relatively small FOV is required, a single partially reflecting surface can be sufficient.
- this angle cannot be trapped inside BK7 or other similar materials. It is true that there are flint optical materials with higher refractive indices, which can exceed 1.8, however, the transparency of these materials is usually not high enough for substrate-mode optical elements.
- Another possible solution is to coat the substrate surfaces not with regular anti-reflection coatings but with angular-sensitive reflecting coatings that trap the entire FOV inside the substrate even for lower angles than the critical angle. It must be noted that even for a non see-through applications, where one of the substrate surfaces can be opaque and hence can be coated with a conventional reflecting surface, the other surface, the one which is next to the eyes of the viewer, should be transparent, at least for the angles of the required external FOV.
- the required reflecting coating should have very high reflectance for the region of angles lower than the critical angle and very high reflectance for the entire FOV of the image.
- the input display source can be located very close to the substrate, so that the overall optical system is very compact and lightweight, offering an unparalleled form-factor.
- the present invention offers flexibility as to location of the input display source relative to the eyepiece. This flexibility, combined with the ability to locate the source close to the expanding substrate, alleviates the need to use an off-axis optical configuration that is common to other display systems.
- the input aperture of the LOE is much smaller than the active area of the output aperture, the numerical aperture of the collimating lens 6 is much smaller than required for a comparable conventional imaging system. Consequently a significantly more convenient optical system can be implemented and the many difficulties associated with off-axis optics and high numerical-aperture lenses, such as field or chromatic aberrations can be compensated for relatively easily and efficiently.
- the reflectance coefficients of the selectively reflective surfaces in the present invention are essentially identical over the entire relevant spectrum. Hence, both monochromatic and polychromatic, light sources may be used as display sources.
- the LOE has a negligible wavelength-dependence ensuring high-quality color displays with high resolutions.
- FIG. 9 illustrates an embodiment of the present invention in which the LOE 20 is embedded in an eye-glasses frame 58.
- the display source 4, the collimating lens 6, and the folding lens 60 are assembled inside the arm portions 62 of the eye-glasses frame, just next to the edge of the LOE 20.
- the display source is an electronic element such as a small CRT, LCD, or OLED
- the driving electronics 64 for the display source might be assembled inside the back portion of the arm 62.
- a power supply and data interface 66 is connectable to arm 62 by a lead 68 or other communication means including radio or optical transmission.
- a battery and miniature data link electronics can be integrated in the eye-glasses frame.
- the embodiment described above can serve in both see-through and non-see-through systems. In the latter case opaque layers are located in front of the LOE. It is not necessary to occlude the entire LOE, typically only the active area, where the display is visible needs to be blocked. As such, the device can ensure that the peripheral vision of the user is maintained, replicating the viewing experience of a computer or a television screen, in which such peripheral vision serves an important cognitive function.
- variable filter can be placed in front of the system in such a way that the viewer can control the level of brightness of the light emerging from the external scene.
- This variable filter could be either a mechanically controlled device such as a folding filter, or two rotating polarizers, an electronically controlled device, or even an automatic device, whereby the transmittance of the filter is determined by the brightness of the external background.
- One method to achieve the required variable transmittance filter is to use electrochromic materials in order to provide electrical control of optical transmittance, wherein materials with electrically controllable optical properties are incorporated into laminated structures.
- electrochromic materials in order to provide electrical control of optical transmittance, wherein materials with electrically controllable optical properties are incorporated into laminated structures.
- FIG. 9 is just an example illustrating the simple implementation of the present invention. Since the substrate-guided optical element, constituting the core of the system, is very compact and lightweight, it could be installed h a vast variety of arrangements. Hence, many other embodiments are also possible including a visor, a folding .
- HUD head-up displays
- Fig. 10 illustrates a method of materializing an HUD system based on the present invention.
- the light from a display source 4 is collimated by a lens 6 to infinity and coupled by the first reflecting surface 16 into substrate 20. After reflection at a second reflecting array (not shown), the optical waves impinge on a third reflecting surfaces 22, which couples the light out into the eyes 24 of the viewer.
- the overall system can be very compact and lightweight, of the size of a large postcard having a thickness of a few millimeters.
- the display source having a volume of a few cubic centimeters, can be attached to one of the corners of the substrate, where an electric wire can transmit the power and data to the system. It is expected that the installation of the presented HUD system will not be more complicated than the installation of a simple commercial audio system.
- Fig. 10 can be implemented for other applications, in addition to HUD systems for vehicles.
- One possible utilization of these embodiments is as a flat display for a computer or television.
- the main unique characteristic of such a display is that the image is not located at the screen plane, but is focused at infinity or to a similarly convenient distance.
- One of the main drawbacks of existing computer displays is that the user has to focus his eyes at a very close distance of between 40 and 60 cm, while the natural focus of. a healthy eye is to infinity. Many people suffer from headaches after working for a long duration of time at a computer. Many others who work frequently with computers tend to develop myopia.
- a flat display based on the present invention, could be an appropriate solution for people who suffer from the above-described problems and do not wish to work with a head-mounted display.
- the present invention allows for a significant reduction in the physical size of the screen. As the image formed by the LOE is larger than the device, it would be possible to implement large screens on smaller frames. This is particularly important for mobile applications such as lap and palm-top computers. Yet another possible implementation of this embodiment is as a screen for a personal digital assistance (PDA). The size of the existing conventional screens which are presently used, is under 10 cm.
- the minimal distance where these displays can be read is on the order of 40 cm
- the obtainable FOV is under 15°; hence, the information content, especially as far as text is concerned, on these displays is limited.
- a significant improvement in the projected FOV can be made with the embodiment illustrated in Fig. 10.
- the image is focused at infinity, and the screen can be located much closer to the eyes of the viewer.
- each eye sees a different part of the total filed-of-view (TFOV), with an overlap at its center, another increase in the TFOV may be achieved. Therefore, a display with an FOV of 40° or larger is feasible.
