摘要: Random-phase distributions that are statistically independent individually used for computing kinoforms. These uncorrelated kinoforms recorded and read out sequentially by a phase-only liquid-crystal spatial light modulator, reconstructed images with well-developed speckles added. The fidelity of the resultant image to an original is improved as number additions increases. dependence speckle contrast on initial random phase influence modulator's display performance quality discussed.
