Abstract

A new and practical method for achieving color electro-holographic display systems was developed and tested with very promising results. In proposal method, virtual image reconstruction method and color hologram reconstruction techniques utilizing a single white light source, instead of the traditional three color laser lights, and three liquid crystal display panels (LCD) were proposed.. In this method imaging lens is not necessary and we can get wide viewing angle. A metal halide lamp with good specifications in each wavelength of the color components was adopted as the light source. Each of the three color light components required for the reconstruction of an image was extracted by color separation using dichroic mirrors. The separated color images were then reconstructed by the hologram formed on the LCD panels which is then combined togethre through the use of a prism to form a single 3D image. As the result system become compact and realistic one.
