摘要： A display can be utilized with an image source. The display includes a collimator and a substrate waveguide. The substrate waveguide sees collimated light from the collimator at an input and provides the collimated light to an output. The collimated light travels from the input to the output within the substrate by total internal reflection. An input diffraction grating is disposed in a first area at the input and an output diffraction grating is disposed in a second area at the output. The second diffraction grating is matched to the first diffraction grating. A combiner alignment detector is not required due to the periscopic effect according to one embodiment.

摘要： A present novel and non-trivial system, apparatus, and method for employing a catadioptric optical system in a Head-Up Display (“HUD”) system are disclosed. A catadioptric optical module is configured to produce a large image size within a small space envelope by folding the optical path back through module and separating the paths by use of a beam splitter. Such module comprised of a beam splitter, collimating mirror, and correcting lens produces collimated beams of light from an image source providing either polarized or non-polarized beams of light. If polarized beams are provided, the module includes a quarter-wave retarder, and the configuration of the module permits the image source to provide either s-polarized or p-polarized beams. A combiner arm assembly comprising of at least one combiner receives the collimated beams, where the employment of a plurality of combiners extends the relatively small instantaneous field of view.

摘要： A head up display (HUD) includes an image source, a first lens, a second lens, a focusing mirror, a polarizing beam splitter, a second beam splitter and a combiner. The first lens is disposed between the image source and polarizing beam splitter. The second lens is disposed between the polarizing beam splitter and the second beam splitter. The polarizing beam splitter is disposed between the first lens, the mirror, and the second lens. The optical system for the HUD forms an intermediate image between the second lens and the second beam splitter. The intermediate image is located at the focal point of the curved combiner, and therefore the curved combiner collimates the display light upon reflection. The HUD can be compact and have a wide field of view.

摘要： A display (for example, a head up display (HUD)) includes a substrate waveguide. The substrate waveguide can act as a combiner. The substrate waveguide receives collimated light an input and provides the collimated light to an output. The collimated light travels from the input to the output within the substrate waveguide by total internal reflection. An input diffraction grating is disposed in the first area at the input and an output diffraction grating is disposed in the second area at the output. A plate covers at least a portion of the second area. The plate can protect the diffraction grating and reflect transmitted order light from the diffraction grating to improve efficiency.

摘要： A multi-color optical display system (10) employs a multi-powered reflective combiner (20) that together with a monochromatic or partly color-corrected relay lens (16) longitudinally corrects a multi-colored image. The combiner typically includes two surfaces (82, 90) of different optical powers with a reflective coating (106, 108) on each of the surfaces. The coatings are chosen to each reflect a specific wavelength range of colored light used in the system and to transmit all other wavelengths. The curvature of each surface is dictated by the aberrations in the color image created by the relay lens. Specifically, each surface is positioned so that its focus (86, 94) coincides with the focal point (58, 60) of the corresponding color component in an intermediate image (18) created by the relay lens so that the final virtual image (22) reflected by the combiner is longitudinally color corrected.
