A stereoscopic television/video system which provides true stereoscopic imaging without the use of glasses or other viewer encumbrances, and which is compatible with current storage, processing, pick-up, and broadcasting equipment as well as standard band-widths and formats, produces a composite video signal containing two images, which signal when received and displayed on a video display screen produces a manifestation containing two horizontally-disparate views of an object scene. Positioned at one of a set of mathematically defined loci in front of the video screen is a transparency consisting in vertically-oriented elements of two types: active elements which deviate light paths from the video screen, and passive elements which transmit light paths from the video screen to the viewer without deviation. The transparency by virtue of its positioning with respect to the video screen and because of the mutual alternation, width, respective light-redirecting properties, and spatial orientation of its elements, acts to optically and spatially dissociate the two-image manifestation such that each of the viewer's eyes can see but one of the simultaneously displayed images.
