Abstract: An autostereoscopic presentation system (10) that allows a perceived three-dimensional volumetric image (26) to be viewed without any viewing implements. The system (10), in its preferred embodiment, consists of an enhanced film strip (12) having first and second photographic frames (14), (18) where each frame consists of a two-dimensional optical image (16), (20) further having a conventional image (16a), (20a) and a matted image (16b), (20b). The film strip is back projected onto two stationary screens (30), (32) that are juxtaposed in planar separation and where each screen operates in either a translucent mode or a clear mode. A timing and synchronizing circuit (40) in combination with a pair of light responding circuits (48), (49) selects and controls the operational modes of the screens (30), (32) and synchronizes the screen operational modes with the respective alternating projection of the two-dimensional optical images (16), (20). By rapid alternate projections of the optical images onto the screens (30), (32) that are operating in their respective operational mode, the perceived three-dimensional image is produced.
