  • Patent number: 4421379
    Abstract: A two step process allows a multiple holographic lens to be recorded with a single exposure. A multiple exposure, non-overlapping holographic fly's eye lens is first prepared with the correct F number spacing. A single collimated beam striking the fly's eye lens results in a multiple refracted beam array which is allowed to interfere with a second reference beam on a photographic plate. The resulting multiple holographic lens will have equal intensity playback beams, no distortion cross product terms, and improved optical efficiency over multiple superimposed exposure lenses.
