本文提出一种串联式三随机相位板图像加密的新方法，该方法充分运用计算全息记录复值光场的特性以记录加密图像，在传统的双随机相位加密系统基础上，置人第三个随机相位板在输出平面上，对输出的计算全息图进行相位调制加密，引入了新的密钥，获得很好的双密钥效果!同时由于计算全息周再现的多频特性，解密须正确提取单元频谱，进一步提高了图像传输的安全性。

A new image encryption technology of three random phase plates is proposed.Recording the encrypted image by CGH with it＇s features of Recording the value of optical field in this method,the third random phase plate was placed on the output plane in the 4f double random phase encryption system to modulate and encrypt the phase of the CGH,there are new keys,the third random phase plate,the exact drawing of the spectrum uint with the multi-frequency characteristics of CGH,which further improve the image transmission security.
