Abstract
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.

Claim 1
Independent Claim
184 words
A method of decoding three-dimensional information addressable by three coordinates, comprising the steps of (a) defining an origin point; (b) analyzing the information content of the point and providing a corresponding output; (c) determining whether the last point analyzed is the last point along a first coordinate axis; if not, advancing to the next point along the first coordinate axis and returning to step b; if so, advancing to step d; (d) determining whether the last point analyzed is the last point along a second coordinate axis perpendicular to the first; if not, advancing to the next point along the second coordinate axis, returning to the origin point along the first coordinate axis, and returning to step b; if so, advancing to step e; and (e) determining whether the last point analyzed is the last point along a third coordinate axis perpendicular to the first and second coordinate axes; if not, advancing to the next point along the third coordinate axis, returning to the origin points along the first and second coordinate axes, and returning to step b; if so, returning to step a.

A method of decoding three-dimensional information addressable by three coordinates, comprising (a) defining an origin line perpendicular to and at the intersection of a first coordinate axis and a second coordinate axis; (b) analyzing the information content of the line, determining the position of the information along the first coordinate axis, and generating a corresponding output signal; (c) determining whether the last line of information analyzed is at the last point along the first coordinate axis; if not, advancing to the next point along the first coordinate axis and returning to step b; if so, advancing to step d; and (d) determining whether the last line analyzed is at the last point along the second coordinate axis; if not, advancing to the next point along the second coordinate axis, returning to the first point along the first coordinate axis, and returning to step b; if so, returning to step a.
