摘　　要：光波作为信息载体具有高速并行处理二维信息的能力及天然优势。光波的波长、振幅、相位、偏振等为光波的调制提供不同的维度和多种可能,也使得光学加密技术和光学密码系统展现出巨大的应用价值。随着加密数据传输量的急剧增长,在进行加密的同时实现信息的压缩变得愈加重要,因为这将缩短处理这些数据所需的时间并有效节约存储空间。提出广义的光学图像压缩加密的概念,并将压缩策略分为明文压缩、密文压缩和明文密文同步压缩。在此基础上,介绍适合每种策略的具体压缩方法,并通过阐述这些压缩方法在一些实例中的应用,综述了光学图像压缩加密技术的研究进展,也对未来的研究方向进行了展望。Optical waves as information carriers can process twodimensional information in parallel with high speed and have many degrees of freedom(e.g.,wavelength,amplitude,phase,and polarization).Therefore,optical encryption technologies and optical cryptosystems demonstrate great potential for applications.With the rapid growth of encrypted data transmission volume,it becomes increasingly important to realize information compression while encrypting because it shortens the time required to process these data and substantially saves storage space.In this paper,we propose the concept of generalized optical image compressionencryption and categorize its compression strategies into three types,including plaintext,ciphertext,and synchronous compressions.On this basis,the specific compression methods suitable for each strategy are specified,and the research progress of optical image compressionencryption is introduced by describing the applications of these compression methods at some instances.Moreover,the potential future research directions of optical image compressionencryption are also presented.
