Three-Dimentional Image Information Media. Electro-Holography Design using MIM Liquid Crystal Display Devices.

Holography is an ideal technique for 3 D displays. However, since precise modulation of light waves is required, it has long been very difficult to achieve electro-holography. Recently, however, some demonstrations of electro-holography using liquid crystal devices were presented. In this paper, we describe the process, characteristics, and driving methods of a liquid crystal device that aims for a fine pixel structure. Then, we discuss the design of an electro-holography system for the viewpoint of the spatial frequency of the hologram. We also experimentally examine the influence of the pixel structure on image quality by comparing electro-holography and optical holography images.
