A Technique for Producing Wide-Angle Holographic Displays

Abstract

A new technique has been devised for recording and reconstructing holograms which can be viewed from a wide range of angles simultaneously by a large number of people. The problems which arise through the use of this technique have been analyzed and the limitations delineated. Satisfactory wide angle, three-dimensional displays have been constructed in the manner described by using absorption holograms. The features of these holographic displays agree qualitatively with the predicted theoretical limitations.
