    摘要: 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.

    摘要: Light scatter control is provided in rear projection and front projection of light images focused upon a screen having a liquid crystal droplet film, and modulated light gain control of single and multi panel screens is provided, without size restriction, maximizing light transmission and reflection, for brilliant high resolution viewing of cinema and video regardless of high degree of ambient light. Panels of liquid crystal film lamina and associated laminates are joined by imperceptible optical splicing.
