Abstract
A holographic apparatus uses electronically processed three-dimensional information about an object to produce a three-dimensional display of that object and its movement. A holographic screen has a plurality of angularly multiplexed holographic images which are selectively illuminated by a modulator and light source to produce the three-dimensional surface outline of the object to be seen. Color encoding and rapid sequential presentation of images gives the effect of a full-color, three-dimensional 'television' in which movement of the object and both horizontal and vertical parallax can be provided.
