摘　　要：偏振成像技术的优势是把信息量从3个自由度,即光强、光谱和空间,扩充到7个自由度,包括光强、光谱、空间、偏振度、偏振方位角、偏振椭率和旋转方向,这种观测信息量的丰富有利于提高对研究目标探测的精确度。本文首先介绍在近几十年内偏振成像技术在国内外的研究进展,其次介绍偏振技术在军事及民用领域的典型应用,最后对我国在偏振成像技术方面存在的问题给出合理的建议。The advantage of polarization imaging technology is that it expands the amount of information from three degrees of freedom,namely light intensity,spectrum,and space,to seven degrees of freedom,including light intensity,spectrum,space,degree of polarization,polarization azimuth,polarization ellipticity,and direction of rotation.This richness of observational information is conducive to improving the accuracy of research target detection.This article first introduces the research progress of polarization imaging technology at home and abroad in recent decades,then introduces the typical applications of polarization technology in military and civilian fields,and finally provides reasonable suggestions on the problems of polarization imaging technology in our country.
