Abstract
We numerically investigate the performance of the proposed system. The noise caused by the quantization in the computer generated hologram (CGH) is analyzed. We also verify experimentally the proposed system. A photorefractive lithium niobate crystal is used as a recording material to store the joint power spectrum. We confirm that there is successful encryption and decryption
