HOLOGRAPHIC VIDEO SYSTEM WITH A PULSE LASER

A holographic video system operated by a pulse laser is described. The use of a pulse laser as the light source allows the polygon mirror (o r scanners) in the system to be eliminated. At the same time, a single long aperture acousto-optic modulator (AOM) is replaced by 6 small ap erture AOMs linearly aligned and a still polygon mirror set is used. T he effective aperture length of the 6-AOM-combination is 6 times that of an individual AOM. Since in this system the computer-generated-holo gram (CGH) data is divided into 6 equal parts and loaded into the corr esponding AOMs independently and synchronously, the loading time of CG H data to an AOM is reduced. This system can display 36.864 (in the ho rizontal direction) x 128 (in the vertical direction) holographic frin ge data points in binary format and operate at a rate of 60 frames per second using a personal computer.
