摘要
用光纤面板对彩色图象取样并压缩成三基色象,写入液晶光阀,用激光读出,然后实现加密全息记录。利用同一装置又可恢复原彩色图象。文章讨论了存储与恢复的原理,结出了实验过程与结论。
A color image can be sampled and compressed into its three primary color images by a fiber faceplate. Written into a liquid crystal light valve,these three primary color images can be read through a polarizing beam splitter with a laser beam. Then ,the read-out images can be crypto graphically stored by means of holography. The original color image can also be retrieved by the same instrument handled in the opposite direction. In this paper,the principle of the storage and retrieve is discussed,and its experimental processes and conclusions are presented too.
