Abstract : The report describes the results of a program to apply recent advances in the area of volume phase holographic materials for map storage and display applications, and to develop and evaluate subsystem components and techniques for this purpose. The major achievement of this program was the recording and fixing of up to 100 holograms in a given volume using a new technique for fixing in heavily iron-doped LiNbO3. In addition, a mechanical random-access system for retrieving up to 100 holograms was developed and tested. An investigation was made of direct and indirect display formats, including incoherent readout of thick phase holograms and the recording and playback of encoded object transparencies on a color kinescope. This led to the conclusions that electronic pickup of the readout image is required for maximum use of the potential of a volume holographic storage system. (Author)
