我们与双地加密的信号和参考书波浪建议一个安全数字 holographic 系统。二个随机的阶段面具被用来在输入和 Fourier 飞机加密图象。参考横梁是另一个随机的阶段面具编码的阶段。加密图象和钥匙被一个电荷耦合器件照相机记录。数据能被计算机直接处理或转。我们理论上并且试验性地证明多重图象和结果的加密和解密显示出高质量和好容错。
We propose a secure digital holographic system with signal and reference waves dually encrypted. Two random phase masks are used to encrypt the images in the input and the Fourier planes. The reference beam is phase encoded by another random phase mask. The encrypted image and the key are recorded by a CCD camera. The data can be processed or transferred directly by computer. We theoretically and experimentally demonstrate encryption and decryption of multiple images and the results show a high quality and good fault tolerance.
