摘要： A head up display includes an image source, collimating optics, and a combiner. The collimating optics are disposed between the combiner and the image source. The combiner receives collimated light from the collimating optics at an input and provides the collimated light to an output. The collimating light travels from the input to the output within the combiner by total internal refraction. An input diffraction grating is disposed in a first area and an output diffraction grating is disposed in a second area. The first area is smaller than the second area.

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 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.

摘要： A scene imaging system (SIS) integrity monitor for monitoring the required operation of an imaging sensor of an SIS. The SIS is of a type including: i) an imaging sensor, ii) an imaging system processor, and iii) an imaging system display. The SIS integrity monitor includes a signal emitter assembly for receiving emitter drive signals from an imaging system processor and directing a monitoring image into the active field of view of an imaging sensor for sensed image generation. The generated image is provided to the imaging system processor for analysis. The imaging system processor evaluates the location and modulation state of the generated image to determine if faults exist in the image generation or image display paths.
