Paper Abstract

In this paper, we suggest a simple method of making specified random-phase shifters which are used for speckle-shift multiplexing in photopolymers. Compared with other kinds of diffusers, they are easier to be made and designed to control the average speckle size so as to accommodate the requirement for high storage density. The experimental scheme and the theoretical calculation of the desired speckle size are given. Then the difference between the experimentally measured and theoretically calculated speckle size is discussed. Finally the unfavorable factors which influence the performances of shift-multiplexing using this scheme are discussed, and the feasible solutions to those problems are given.
