为了实现对运动目标或变化场景的同时成像，根据偏振成像原理，基于孔径分割技术设计了一套微光偏振成像系统.开展了微光偏振成像实验，在实验室条件下定性分析了偏振成像的优势，研究了不同照度下偏振成像的准确度.通过改变偏振出射光束的照度，运用获得的偏振图像计算了该照度下光束的偏振度和偏振角.与真实偏振度、偏振角信息对比分析表明，当环境照度大于10-2 lx时，偏振成像能够比较准确地还原场景的偏振信息，改善微光成像质量.经过优化，该系统MTF在56 lp/mm处所有视场下均不小于35%.

According to polarization imaging theory, at least three linear polarized images of the same scene were required. A polarization imaging system based on division of aperture technique was designed in this paper so that the moving objects or a rapid changing scene was able to be imaged simultenously. The system MTF in all the view fields at 56 lp/mm was no less than 35% after optimization. Finally, polarization imaging experiments were conducted in a low light level condition and experimental results were analyzed qualitatively. Moreover, polarization imaging precision versus illumination was intestigated. By changing the incident illumination level and computing the acquired polarization images, the degree of polarization and angle of polarization were compared with the corresponding true values. The results show that polarization imaging can improve the quality of low light level images.
