Last year at the 1993 conference on Holographic Imaging and Materials, the author presented a real-time holographic stereogram resembling a Lloyd Cross cylindrical holographic stereogram. It employs a cylindrical HOE that spins at 30 rotations per second and displays 25 real-time raster scanned 2D images of electronic data. It allows the viewer significant freedom of movement in any direction, while viewing the 3D images, and the ability to look around objects by intuitively moving one's head. However, an ideal 3D display would not have any moving parts, and would be flat panel. In this paper a flat panel real-time holographic stereogram with no moving parts is presented. This simple 3D display is ideal for both consumer and industrial use.
