Three-Dimensional Image. Real-time Stereogram Display Synthesized with an Optical Hologram for Rich Images.

One of the most useful ways to display 3-D images is with a real-time stereogram system using a holographic optical element (HOE) This simple display system presents stereoscopic 3-D images that can be without special glasses, but the quality of the images is not as good as that of images reconstructed from an optical hologram This paper shows that this problem can be solved by synthesis of a screen HOE and an optical hologram In addition, a newly developed method for making a screen HOE that is easy to synthesize is described Experimental results in this paper demonstrate the feasibility of this expressive holographic display
