Electroholography is a technology that displays three-dimensional images using electrocommunication. Because it has the potential to satisfy the physiological aspects of vision, such as parallax, convergence and focusing, electroholography is often said to be the ideal three-dimensional display. However, it has never been commercially realized because of technical difficulties. Recently, there have been advanced developments in microfabrication and computers, which are used in electroholography. The first electroholographic system, proposed by Professor Benton’s group (Massachusetts Institute of Technology) in 1990, showed color three-dimensional movies. The system had strong impact on the field, and indicated the capabilities of electroholography. Subsequently, many researchers were inspired, and attempted to make various systems. Last year, a prototype using a new method was developed. Although it is still not the ideal electroholography, it shows commercial potential. This paper reports on the progress of electroholography, problems be resolved, and prospects for the future.
