Paper Abstract

This system for stereoscopic television uses relative camera to scene translating motion and does not require optical aids at the observer's eyes, presents a horizontal parallax (hologram like) 3-D full motion scene to a wide audience, has no dead zones or pseudo 3-D zones over the entire horizontal viewing field and operates on standard telecast signals requiring no changes to the television studio equipment or the home television antenna. The only change required at the receiving end is a special television projector. The system is compatible with pre-recorded standard color television signals. The cathode ray tube is eliminated by substituting an array of solid state charge couple device liquid crystal light valves which have the property to receive television fields in parallel from memory and which are arrayed 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. These 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 that returns all of the light to a rapidly translating vertical "aerial" exit slit of light through which the audience views the reconstructed 3-D scene.
