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.
