利用随机位相编码技术对光学图像进行保密

The Methods of the Optical Image EncryptionUseing Random Phase Encoding

本文介绍了一种利用随机位相编码技术对光学图像进行保密的方法．该方法是利用两个随机位相掩模将振幅识别的初始图像编码为复振幅稳定的白光噪声，使仅对光强敏感的探测器无法接收．保密图像再现所采用光学方法具有最大的光学效应．

In this paper,we introduce a method of the optical image encryption based on a ran-dom phase encoding technology.This method can encode a primary image into a complexamplitude/phase stationary white noise using two random phase masks, which can not beseen by an intensity detector. The reconstruction method can be implemented optically withmaximum optical efficiency.
