保密存取光学图象的一种重要方法

An important method to store and take optical image secretly

本文叙述了一种对图象保密存取的光信息处理系统．该系统采用付氏滤波对图象加密，采用相干光反馈系统（ＣＦＳ）对图象解密。其实验结果证明了系统的可行性。

This paper describes an optical information processing system. The system realizes successfully image coding using Fourier filter and image decoding using coherent optical feedback system. The experiment result shows the availability of the method.
