A stereoscopic television arrangement which does not require optical aids at an observer's eyes uses a plurality of sequential television frames or fields, each representing a different view of a scene and obtained, for example, by providing relative lateral motion between a television camera and the scene. The television frames are fed in parallel from a memory to an array (2) of solid state charge coupled device liquid crystal light valves arranged in an arc for scanning purposes. The array contains a scrolled sequence of successive television frames which serve as the basis for 3-D horizontal viewing parallax. The light valves reflect polarized light with the degree of polarization made a function of the scene brightness. The array is optically scanned and the sequence rapidly projected onto a cylindrical concaved semi-specular screen (12) that returns all of the light to a rapidly translating vertical exit slit (13) of light through which the audience views the reconstructed 3-D scene. <IMAGE> |
