为了实现对动态目标场景的偏振成像，设计了双分离渥拉斯顿棱镜同时偏振成像系统。该系统将分振幅与分孔径相结合，在两个探测器上同时获得四幅偏振分量图像，实现动态场景的偏振成像。在简述系统设计原理的基础上，重点介绍系统光学系统、核心器件以及系统光机结构的设计，并分析系统的偏振成像实验。实验结果表明：系统偏振分光性能较好，四幅8 bit偏振消光图像的残留灰度均在15以下；外触发信号同步控制透射和反射光路，系统最高帧频可达90 Hz，在帧频为25 Hz时同步采集了动态场景的偏振图像，并分析了场景的偏振度和偏振方位角信息，实现了动态场景的偏振成像；系统能够对最近成像距离以外的任意距离的目标清晰成像，系统分辨率达到76.9 cyc/mrad。

In order to realize polarization imaging of dynamic scene, a simultaneous imaging polarimetry with double separate Wollaston prism is designed. This system is a combination of division-of-amplitude and divisionof-aperture, which can achieve four polarization images simultaneously on two detectors synchronized by external trigger. The principle of the system is briefly illustrated, and the design of optical system, choice of core devices and opto-mechinal design are emphatic introduced. The polarization imaging experiments of system are analyzed. The experimental results show that system performance on polarization splitting is well, and the residual gray level of polarization extinction image is under 15 with four 8 bit detector; the maximum frame rate can reach 90 Hz with external trigger, and polarization image of dynamic scene is sampled at 25 Hz; the system can focus on any distance larger than the nearest image distance, and system resolution reaches 76.9 cyc/mrad.
