Holographic stereogram movie system for practical 3D display

A display system requiring no special glasses is a useful technology for 3D images. The authors have researched real- time holographic stereogram displays using a holographic screen. In June 1995, we presented the stereoscopic 3D display system with viewing apertures such as conventional two-step holographic stereogram. In 1996, we introduced the stereoscopic 3D color display system using a holographic pseudo-color technique. Last year at the 1997 conference on Practical Holography, the authors presented the stereoscopic 3D display system based on a reconstruction of parallax- rays. These systems consist of a liquid crystal device and a holographic screen formed of holographic optical elements. These systems can construct animated 3D images in real-time by updating LCD pixels. In this paper, the latest result of our study about a stereoscopic 3D display system is proposed. In addition, this paper presents the result of a holographic stereogram movie system as a future 3D display.
