实现了物光和参考光双加密的数字全息加密方法,并从理论模拟和实验上分别验证了该方案,其安全性远高于仅加密一束光时的情况.使用双随机相位加密法加密了原始图像,并使用随机相位片编码了参考光. 加密后的图像由 CCD 接收后再使用计算机处
理.在实验上检测了该系统的信噪比和容错性, 并计算得到系统的密钥长度高达6.3×1014
.-Object and reference light to achieve a double-encrypted digital holographic encryption method, and from theoretical modeling and experimental validation of the program, respectively, its safety is much higher than the case when a beam of light is only encrypted using double random phase encryption encryption the original image, and use the random phase encoded reference beam slice. encrypted and then received by the CCD image processing using a computer in the experiments on the detection signal to noise ratio of the system and fault tolerance, and calculated the length of the key system up to 6.3 × 1014.
