摘要： An aircraft head up display system that displays a basic mode, an en route mode, or an approach/landing mode. When the aircraft attitude changes to predefined unusual attitude conditions, the display changes to an unusual attitude mode to indicate the unusual attitude condition. The display in the unusual attitude mode removes non-essential symbols and displays the aircraft air speed, altitude and attitude. The attitude display includes an unusual attitude ball display containing a horizon symbol, a series of simulated section lines to indicate an area below the horizon, a pitch ladder, a water line indicator, and a roll indicator.

摘要： An optical display system employs a holographic optical element that has a holographic fringe pattern which is coordinated with the phosphor emission peak of a cathode ray tube to eliminate perceptible variations in image brightness. The holographic optical element has a reflection characteristic that defines two diffraction efficiency peaks which are resolved by a low diffraction efficiency dip that is interposed between them. The optimum wavelength spacing between the two diffraction efficiency peaks for a given wavelength spacing is determined by computing for all observer head positions and look angles of concern the differences among the areas under the integrated efficiency characteristics for the reflection characteristic of the holographic optical element and the phosphor emission characteristic of the image-producing cathode ray tube. The optimum wavelength spacing is that which provides the desired variation among the computed difference values, which respresent the display brightness uniformity. The center dip reflection characteristic increases the spectral bandwidth of the holographic optical element and thereby increases its reflectivity to promote good contrast with the use of a cathode ray tube operating at reduced beam current levels. When installed as a combiner in a head-up display sytem for aircraft, the holographic optical element superimposes the image on an outside scene without introducing significant discoloration of the scene.

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： An optical display system (10) presents visual source information to an observer (18) The display system includes a vision unit (14) that has reflective surfaces (16) through which the observer can view an outside world scene and which reflect source information emanating from an information source (22) for display to the observer In a preferred embodiment, the optical display system constitutes a head-up display system for an automobile and the observer is the driver of the automobile. The vision unit constitutes an automobile windshield with or without a reflection enhancement material and whose inner and outer surfaces reflect source information carried by light propagating form the information source, such as a liquid crystal display (32). A projection lens system (24) positioned between the inner surface of the windshield and the information source has optical light-directing properties for compensating for optical aberrations introduced by the nonplanar windshield surface. The projection lens system includes an aspheric element (262) that is unique to a specific aspheric windshield shape and remaining elements that are common to a great number of different windshield shapes. A positioning mechanism ( 130) allows the driver to adjust the vertical position of the source information (60) reflected by the windshield within a total display field of view for optimal viewing by a seated driver. The positioning mechanism also automatically changes the distance between the display image and the driver as a function of vehicle speed to promote safe vehicle operation.
