    摘要: A star tracker for generating positional information for a vehicle includes a holographic telescope (150) having one or more fields of view for imaging stellar objects. The telescope includes a plurality of radiation detectors (100) and an input aperture comprised of a primary holographic optical element (HOE) (134). The primary HOE provides one or more wavefronts to one or more secondary HOEs (136), each of which applies a chromatic correction so as to correct for a chromatic aberration induced by the primary HOE. A single or multiple field of view Schmidt telescope embodiment is also disclosed having one or more aspheric corrector plate HOEs and one or more associated concave spherical reflectors.

    摘要: Improved optical holographic apparatuses are disclosed for making white light viewable rainbow holograms in one step utilizing concave mirror optics. On-axis and off-axis configurations are presented for holography of real objects and for reduced image holography of a real image projection from a laser transmission hologram. An optical apparatus and curved recording devices are devised to reduce and/or eliminate certain aberrations introduced by the concave mirror. To yield a wide holographic field of view at low cost, small diameter mirrors are employed in two alternative devices for replacing a single concave mirror in the various embodiments. Two methods are then presented to obtain reduced image size one-step rainbow holograms from a full size object or holographic image. Finally, a method is given for specifying the radius of curvature and minimum effective aperture of a concave mirror system in one step rainbow holography that maintains image aberrations at acceptable levels and yields the desired field of view.
