摘要
偏光全息术通过记录两束偏振光干涉形成的偏振光栅,可以把偏振光信息存储在偏振敏感材料当中。偏光全息把传统全息术中长期被忽视的光波偏振信息加以利用,在加大了存储容量的同时,也具有了许多独特的性质。本文简要介绍了偏光全息的发展历程,描述了基于张量的偏光全息理论及其一些推论,然后对偏光全息在数据存储领域的应用作了介绍,并做出展望。
By recording the polarization grating formed by the interference of two polarized lights,polarization holography can store the information in polarization sensitive materials.In contrast to traditional holography,polarization holography owns many unique properties,for instance,utilizing the long-neglected polarization information and increasing storage capacity.This paper first briefly introduced the development of polarization holography,the tensor-based holographic theory and some of its inferences.Then the further applications of polarization holography in high density data storage are briefly overviewed.
