| 摘 要： | 基于联合变换相关系统,采用嵌套的投影限制集算法(projection onto constrains sets,POCS),依次得到多个相位掩模,进而用于光学图像加密;在不同的应用条件下,可以输出相应的安全信息,从而实现信息的分级安全共享.文中给出了可实现的光学装置和计算机的模拟结果.

| Abstract: | A novel architecture based on the joint transform correlation system that uses nesting POCS algorithm is proposed.Multiple phase masks can be designed to contribute efficiently to optical image encryption.The system is capable of producting different security information according to the correspoding conditions to realize information classification and sharing.Computer simluation results have been given and the optical implementation setup is also suggested. |
