短波红外偏振成像技术的研究进展

Research progress of short-wavelength infrared polarization imaging technologies

与传统成像系统相比,偏振成像系统通过探测目标物在不同状态下的明显偏振差异,提高对目标物的探测和识别能力,因而被广泛应用于复杂环境或有伪装物的目标探测。特别是短波红外谱范围的信息探测可以提供人眼所不能看见的分辨率和细节,是目前军事和民用领域的重点研究方向之一。这篇综述归纳总结了传统偏振成像系统的结构分类及其特点,探讨了新型微纳偏振成像系统的研究进展,并针对目前短波红外偏振成像技术存在的主要问题提供了可行性分析和建议。

Compared with the traditional imaging systems,the polarization imaging systems are capable of improving the detection and recognition ability of the target by detecting the obvious polarization differences of the target in different states.Therefore,they have been widely used in complex environments or target detection with camouflage.In particular,the information detection in the short-wavelength infrared spectrum range can provide high resolution and details that cannot be seen by the human eyes,which is one of the key research directions in the military and civilian applications.First,the structural classification and characteristics of traditional polarization imaging systems were summarized.Then,the recent research progress of new micro-nano polarization imaging systems was discussed.Finally,the feasibility analysis and suggestions for the main problems of the current short-wavelength infrared polarization imaging technologies were provided.
