    摘要： A compact, inexpensive and mass-producible optical display system for an automobile creates a highly visible and sharp, high contrast and pleasing, multi-color magnified virtual image of a primary instrument cluster at a viewing distance which is greater than the actual optical distance between the dashboard and the driver's eyes in order to enhance instrument readability, minimize driver eye strain, and reduce eye focus problems which are associated with transitioning between the far range viewing used for watching the road ahead and the near range viewing used for glancing at the instruments. A non-pupil forming display system uses a single off-axis aspherical mirror with power to create a virtual image of a miniaturized, multi-color passive image source, such as a segmented LCD panel, which is backlighted by a small filament incandescent light bulb. The aspheric surface is optimized to minimize aberrations and reduce vertical disparity and field curvature. The image source is pre-distorted to compensate for distortion in the off-axis configuration. A holographic diffusing screen element laminated onto the image source provides uniform high brightness and uniform contrast over the entire field-of-view which is visible from an eyellipse sufficient to accomodate most of the driver population, minimizes the visual impact of any optical aberrations near the edge of the viewing area, and provides the non-pupil forming system with some of the desirable optical properties of a pupil forming system.

    摘要： An improved optical combiner useful in many applications is disclosed. The combiner includes a substrate with at least one aspheric surface and an diffraction-type reflective coating formed on the substrate for selectively reflecting radiation within one or more predetermined narrow band ranges of wavelengths impinging on the coating. The aspericity of the surface may be selected to compensate or balance optical aberations. The coating is advantageously a graded-index coating, which eliminates the possible degradation of gelatin halogram coatings due to moisture. A process for applying the graded-index coating to a substrate is disclosed. The variation in the index profile of the coating can be selected to provide the capability of combiners with multiple color reflectivity responses, or which allow use of display light sources of wider spectral bandwidth, resulting in a brighter image and improved angular bandwidth. In another disclosed embodiment, the combiner is incorporated in a biocular helmet visor display resulting in improved optical performance and a simpler, lightweight structure. In another embodiment, the combiner is incorporated into a head-up display for an aircraft resulting in improved performance, lower weight, improved safety and greater look-up capability.

    摘要： Optical assembly (34) has a transmission holographic optical element (46) which refracts the incoming ray (38) at an angle through the angularly oriented fiber (56) in fiber optic faceplate (48). Holographic optical element (50) refracts the ray (66) to become ray (44) toward a viewing pupil. The zero-order light from holographic optical element (46) is absorbed as ray (68) in the fiber optic faceplate. The zero-order light represented by ray (76) is absorbed in the holographic optical element (50). Holographic optical element (50) preferably forms a diffused viewing pupil for inspection of the light by the user.

    摘要： A process for depositing on the surface of a substrate a layer of a chosen material having continuous gradations in refractive index in a predetermined periodic pattern. The substrate is exposed to two vapor phase reactants which react upon radiation-inducement to produce the chosen material, and the relative proportion of the reactants is varied in a predetermined and continuous sequence to produce continuous gradations in the stoichiometric composition and refractive index of the deposited layer as a function of thickness. Additionally, predetermined changes in refractive index and/or thickness across the horizontal surface of the substrate may be produced in combination with the change in refractive index as a function of thickness. Diffraction optical elements formed by such a process include various optical filters and reflective optical coatings.
