We present an electro-optical apparatus capable of displaying a
computer generated hologram (CGH) in real time. The CGH is calculated
by a supercomputer, read from a fast frame buffer, and transmitted to
a high-bandwidth acousto-optic modulator (AOM). Coherent light is
modulated by the AOM and optically processed to produce a
three-dimensional image with horizontal parallax.
