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.
