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 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： The present invention constitutes a system for generating an elevator command signal for directing a pilot in guiding his aircraft along a path effective for recovering from hazardous windshear conditions. The system includes a descending mode guidance subsystem (10), an ascending mode guidance subsystem (12) and a switching mechanism (14) for shifting between the two subsystems. The descending mode subsystem includes an acceleration generator (20), a flight path command generator (22), a flight path error generator (24), a descending mode pitch error generator (26), an airspeed control device (28) and a descending mode signal controller (30). These components are connected serially together and operate to form an elevator command signal corresponding to the acceleration required to halt the descent of the aircraft by a fixed altitude level. They also function to control and condition this signal with respect to important flight parameters such as the aircraft's maximum safe angle of attack and the response capabilities of the pilot and aircraft.

摘要： A method of preventing a reduction in image contrast in a head-up display. The head-up display is comprised of a visual information source, a lens, a wavelength selective reflecting element, and a combiner which reflects at least some of the wavelengths from the information source which reflect off the reflecting element. The reflecting element, in addition to being wavelength selective, is provided with optical power to reduce aberrations which would otherwise result from operating the combiner at an off-axis angle.

The signals may be used as the pitch and roll input information in an interactive computerized flight simulation system. The signals may also be generated by an actual pilot of a hang glider or ultralight aircraft and used on board to control ailerons, elevators, rudders, or the like, so as to enhance the performance potentials of these types of aircraft.

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.

摘要： A method for processing exposed holograms to enhance their thermal stability and enable them to withstand a windshield lamination process is disclosed. The secondary processing procedure entails an optional step of applying a moisture barrier to the hologram, followed by heat stabilizing the hologram and storing it in a relatively low humidity environment. Specifically, the exposed holographic material is heated to a peak temperature of about 135.degree. C. and thereafter cooled to provide a thermally stabilized holographic material that maintains its holographic qualities over a relatively broad range of temperatures.

摘要： A method of constructing flare-free reflection holograms uses a light scattering mechanism positioned between a first exposure beam and holographic recording material to remove the spatial coherence from all but adjacent rays within a relatively small angular range before the light rays of the first exposure beam strike the hologram surface. A second exposure beam of spatially coherent light rays interferes with mutually spatially coherent light rays of the first exposure beam to form a primary hologram. Light rays reflected off the holographic recording material noncontacting surface of the substrate interfere with the light rays of the first exposure beam but do not form parasitic hologram recordings because the interfering light rays are not mutually spatially coherent. The size of the region on the scattering device illuminated by the first exposure beam can also be selectively adjusted to determine the angular range of spatial coherence of the exposure beam and thereby create a primary hologram whose thickness is independent of and, if desired, may be made less than the thickness of the holographic recording material.
