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
