Abstract
A real-time holography system includes a matrix liquid crystal display, as used in a liquid-crystal television set, for producing a hologram. An image of an interference-fringe pattern caused by an object light wave and a reference light wave is converted into a video signal by a CCD camera, and the image of the pattern is reproduced on the display on the basis of the video signal. Therefore, a three-dimensional image can be reconstructed in real-time by making a reference light wave on the display.
