Paper Abstract

Two stereoscopic systems are described which permits the observation of a high resolution image by several persons simultaneously and suited to mass production. One is a time- parallel method and another is a time-interlaced method. In the time-parallel stereoscopic display system, by mechanically driving several video projectors according to the observers' eye position, the images projected on a large format convex lenses are varied, the left image rays continuously entering the observers' left eyes and vice versa. In the time-interlaced stereoscopic display system, the image output screen is formed by a transparent type color liquid crystal plate with a large format lens. The lens is arranged so that an image of viewers is projected to the plane of a black-and-white CRT which is positioned behind as a back light of the system. To view the stereo image on the color liquid crystal plate, the alternating left- and right-eye perspectives must be synchronized with an infrared lightening system and the imaging of the viewers on the CRT that the back light distributes the light to the left eyes when the left-eye view is displayed on the color liquid crystal plate and vice versa.
