Abstract
Large format, highly selective display screens can be formed from a plurality of holographic optical elements. In accordance with the teachings of the present invention, systems and methods are described to provide a holographic screen for display of static and/or dynamic projected conventional two-dimensional images, two-dimensional stereograms, and holographic stereograms. One aspect of the present invention includes presenting live-image three-dimensional displays using an array of two-dimensional data projectors. Another aspect includes projecting and enlarging static or dynamic source three-dimensional images (real objects, holograms, or other autostereoscopic images).
