摘　　要：目前国内红外偏振成像技术的研究尚处于初步的实验阶段,需要开展具有针对性的红外偏振成像实验,以支撑红外偏振成像理论和技术的研究。基于高灵敏度的中波制冷焦平面探测器,搭建了中波红外偏振成像系统,并针对特定场景中的典型目标,开展了红外偏振成像实验,获得了有效的实验数据和成像规律,并基于HSV颜色空间对偏振信息图像进行了融合再现实验研究。结果表明:中波偏振热成像可突出光滑表面的轮廓及金属与水泥构件等的差异,有利于对隐藏目标和伪装目标的探测与识别;利用彩色图像融合方法融合热辐射强度、偏振度和偏振角图像是一种可行的偏振图像再现方式,能够综合反映偏振热成像的有效信息。Infrared polarization imaging technology is at primary stage in China, it is necessary to develop the pertinence experimental study that will support the theory and the technologies of infrared polarization imaging. The medium wave infrared polarization imaging system was set up based on medium wave cooled focal plane detector which had characteristic of high sensitivity. Infrared polarization imaging experiments were carried out, and the infrared polarization characteristics of typical targets at some particular scenes were analyzed. The effective experimental data and imaging law were obtained that established the experimental foundation for further theory and technology research, and the fusion experiment about the polarization information based on HSV color space was studied. The results show that MWIR polarization imaging can stand out the iation intensity, degree and angle of polarization is a feasible reproduction mode, and the fusion image reflects the effective information of polarization imaging synthetically.
