Abstract
A system for stereoscopic image display includes a projection device ( ) with modulators ( ) and a polarization splitter prism ( ) for the projection of images with differing perspectives each with differing polarization directions. A holographic screen ( ) has a grid structure that corresponds to a hologram recording of actual screens with differing polarization directions. The incident light beams (A, B) have the effect that two differently polarized images are generated on the holographic screen ( ), where said images can be perceived separately by the left and the right eye by using eyeglasses ( ) with polarization filters.
