Abstract

Holographic data storage requires reference beam encoding for multiplexing and demultiplexing. Electrically switchable holographic composites (ESHC) based on a Polaroid photopolymer films are being investigated as a basis for several types of reference beam encoding devices. A laboratory demonstration reported here recorded four holograms in a photoresponsive storage medium. Both random phase encoding and angle multiplexing approaches were tested. ESHC encoding devices have much higher diffraction efficiency than spatial light modulators used in many other encoding schemes.
