A real-time stereogram display system using a holographic optical element is one of the most useful technologies providing 3-D images because it is simple and does not require the use of special glasses. This kind of display substitutes a holographic lenticular screen for a conventional refractive lenticular screen. We have developed a prototype system based on the stereoscopic principle of reconstructing parallax rays. The trial holographic screen of this display is 50 cells by 40 cells (i.e., it contains 2000 holographic grating cells). Every grating cell consists of 32 various holographic diffraction gratings, so each cell is capable of reconstructing 32 uni-directional parallax rays. This display system can thus present a 3-D image having 50 pixels for horizontally and 40 pixels for vertically (each pixel has 32 horizontal parallaxes).
