Abstract
Implementation approaches are described for image acquisition and playback of three-dimensional (3-D) computer graphics, 3-D television and 3-D theater movies without special glasses. Projection lamps, spatial light modulators, cathode ray tubes, and dynamic scanning are all eliminated by the application of an active image array, all static components and a semi-specular screen. The resulting picture shows horizontal parallax with a wide horizontal view field (up to 360°) giving a holographic appearance in full color with smooth continuous viewing without speckle. Static component systems are compared with dynamic component systems using both linear and circular arrays. Implementation of computer graphic systems are shown that allow complex shaded color images to extend from the viewer's eyes to infinity. Screen geometries and special screen properties are shown. Superposition of computer graphics on real-world pictures is shown feasible.
