Patent US 5,614,941

A system is disclosed for creating stereoscopic images from multiple sources from predetermined lateral directions for forming the multiple images onto a multiple image plane and converging the images into multiple superimposed images on a viewing screen. The viewing screen employs a Fresnel lens and a lenticular lensed surface with horizontal lenticules. No glasses are needed, by one or more persons, to view stereoscopic 3-dimensional images. The source of the multiple images may be multiple cameras, composite multiple image film, video signals, or computer-generated images. In one embodiment, the multiple images are projected each by a respective substantially identical lens and through a folded optical reflective system to a restricted viewing opening in the system housing.
