基于广义相衬法实现了一个带读出器的纯相位光学加解密系统。实验系统已实现与液晶空间光调制器产生二进制相位加密掩模和解密密钥。相位对比滤波器用于显示相位信息。
We have implemented a phase-only optical encryption and decryption system with a readout based on the generalized phase-contrast method. The experimental system has been implemented with liquid-crystal spatial light modulators to generate binary phase-encrypted masks and a decrypting key. A phase-contrast filter is used to display the phase information.
