Paper Abstract

Holographic memory systems provide such advantages as long data storage term, high data density and do not need a power supply. But traditional holographic systems require vibration isolation and are rather complicated. So computer generation of Fourier holograms (CGFH) is proposed. Instead of recording interference pattern, it is calculated on computer. High information density is reached in new method by multiplexing 1D Fourier Holograms. Optical equivalent of the 1D Fourier holograms computer synthesis is listed. Different spatial light modulators are analyzed for displaying CGFH. System for hologram recording is described. Results of recovering information CGFH are also listed.
