基于高灵敏度的中波和长波制冷焦平面探测器，搭建了红外偏振成像系统，针对特定场景中的典型目标，开展了红外偏振试验，获得了有效的试验数据，并对图像进行了定性分析和定量评价。对比研究表明：长波红外偏振成像易受水汽干扰，但图像的平均灰度和平均梯度指标高；中波红外偏振成像抗云干扰和观测人工防伪网能力强，图像标准方差比较高。根据中长波红外偏振成像的特性，在实际应用中可以按需要进行波段选择。

The medium-wave and long-wave infrared polarization imaging systems were set up separately based on medium-wave and long-wave cooled focal plane detectors,which have the characteristic of high sensitivity .Choosing typical targets at some particular scenes,infrared polarization imaging experiments were carried out and some effective experimental data were obtained .The results show that:1 ) the long-wave infrared polarization imaging is more liable to be disturbed by the water vapor,but is better at the characteristics of mean gray scales and gradient; and 2) the performance of medium-wave infrared polarization imaging on anti-jamming from cloud and detecting camouflage nets is better than that of the long-wave infrared polarization imaging.Considering their characteristics,we can select medium-wave or long-wave infrared polarization imaging system according to the requirement .
