Paper Abstract

It is well known that two-phase CGH can only reproduce graphic images with rotational symmetric features. A multi- phase hologram is required to regenerate arbitrary shaped graphic patterns. Also, for the high fidelity reproduction of images, the computer program must be able to handle many pixels with multi phase. We devised a stochastic optimization program that can generate a multi-phase hologram. Since the algorithm and programming technique is so efficient that the program can be used to generate hologram of black and white pictures as well as graphic patterns. We used the CGH program to generate a portrait picture and some graphical patterns with four-phase holograms. The holograms were transferred onto a glass plate with the semiconductor manufacturing techniques
