英文摘要：

Proposes a three-dimensional （3D） optical image cryptosystem in r resneL uo~tta~,l. In the Fresnel domain, 3D optical images are encrypted and decrypted by computational inte- gral imaging system that is implemented with smart pseudoseopic-to-orthoscopic conversion model. Because these parameters of the new system, the wavelength of the incident light, the lens focal length and so on, can be used as the secret keys in the new system,the dimen- sion of secret key is increased, the secret key space is expanded, and the security and anti- attack of the new system are enhanced. It made an important step forward in the develop- ment of utility for the 3D optical information security system. The research can be applied to information hiding and digital watermarking which are needed for information security protection of 3D new media.
