Paper Abstract
In this paper, we proposed a novel optical encryption and decryption method of gray image based on the computer-generated hologram (CGH), the chaos theory and the logical modulation. In the encryption process, the hologram, which is gotten by Fresnel diffraction from the gray image, is modulated with the chaotic sequence, and the output is encryption image. The decryption is an inverse process of encryption. Experiment results verified the security and robustness of the proposed approach. Moreover, the proposed encryption method could be applied in where requires more security and more flexibility as the field of national defense science and technology.
