ABSTRACT:
A three-step process is combined with an edge-lit system to provide a self-contained, maximally-compact holographic display. In one embodiment, a hologram is affixed to an upstanding transparent support plate mounted through the top of a housing in which the hologram is edge-illuminated with white light from a source in the housing immediately beneath the plate to generate brilliant, sharp and deep multi-color images which straddle the hologram plane. In another embodiment, the transparent support plate is mounted in a frame which carries the edge-illumination source. All displays may either be free-standing or wall-mounted, as desired.
