Abstract

An optical system to permit viewing of adjacent stereoscopic images in which the observers each wear a pair of eyeglasses to view the display. Polarizing light filters are positioned in front of each of the stereoscopic images and these filters have different angles of polarization to encode each image. Each eyepiece includes a polarized filter which decodes the image for its respective eye, and a rotatably adjustable prism which deviates the line of sight a sufficient degree that both stereoscopic images are fused in the fovea of the eye. The rotatably adjustable prism can be a solid prism or a Fresnel prism and Fresnel prisms are preferred. The rotation of the prism permits the observer to adjust the refractory angle of the image regardless of the observer's distance to the image source, and thus permits the observer to move about the displayed images and permits a plurality of observers to view the display.
