Paper Abstract

Multi-valued phase patterns were multiply recorded by retardagraphy in order to improve recording density and data transfer rate. In the experiment, the phase pattern consists of four values were recorded on a polarization-sensitive medium by focusing the recording beam, and three patterns were multiply recorded by shifting the focal point. The recorded patterns could be independently reconstructed.
