In this paper, a new kind of random phase shifter is proposed which is made of photopolymer plate by recording speckle patterns in it. The spectrum distribution of this phase shifter in 2-dimensions is measured and compared with that of random phase shifter made of silver halide plate. The result shows that the spectral distribution of the former is more intense and uniform over a more round area than the latter. An image storage experiment demonstrates that a high-quality image can be retrieved if this speckle random phase shifter is used for Fourier transform hologram recording.
