Abstract: A multicolor display system including a viewing screen having a multiplicity of closely spaced photoluminescent segments thereon in a regular array of alternating red, blue and green segments. A hologram which was recorded at or near the Fourier transform plane of the input information is positioned relative to the screen to project an image of the recorded information thereon when the hologram is illuminated by a readout beam. The information is recorded in a coded format representative of multiple colors contained in the original subject from which the information was derived.

Abstract: An unaided stereo viewing system using a hologram as a rear projection screen. The hologram, by having two sets of interference patterns recorded thereon, has the property that, if a stereo pair of transparencies is projected thereon by the conjugates of the two reference beams used to record the interference patterns, light from one image is diffracted into the right eye of an observer and light from the other image is diffracted into the left eye. A plurality of alternating sets of interference patterns provide a plurality of stereo viewing zones.
