Abstract
In multi-hologram recording, a simple system to implement rotational, angular, and spatial multiplexing efficiently together is proposed and experimented. The methods of both rotational and angular multiplexing are obtained by controlling the reference beam directly by the use of a pair of wedge prisms, while the method of spatial multiplexing is obtained by shifting the recording medium. The proposed system structure makes it easy to realize a practical holographic memory system by simplifying the control of three complex mechanical motions that are necessary for the three multiplexing techniques.
