Abstract

This paper reviews the recent research in the development of three-dimensional optical memories based on phase-code and rotation multiplexing. The theory of phase-code multiplexing as well as rotation multiplexing is discussed. The construction of generalized Hadamard phase codes is presented that ensures the full utilization of the limited number of pixels of currently available spatial light modulators (SLMs). The preliminary experimental results are provided. A demonstration system with off-the-shelf devices is proposed
