Polarization detecting device for detecting low-altitude small target with slow-speed

The embodiments of the invention discloses a polarization detecting device for detecting a low-altitude small target with a slow-speed. The polarization detecting device comprises an optical system used for forming an optical path and generating a polarized image; a detector used for detecting lights passing through the optical system; an exposure control system cooperates with the optical systemand used for controlling the detector to be exposed at a preset time point; an image processor used for processing the polarized image to obtain a degree of the polarization and an image of the polarization angle; and a mechanical support system used for supporting and connecting the optical system and the exposure control system. The polarization detecting device for detecting the low-altitude small target with the slow-speed has the advantages of large detection range, high resolution, high signal-to-noise ratio and quasi real-time. 本发明实施例公开了种用于探测低空慢速小目标的偏振探测装置。该偏振探测装置包括用于形成光通路并生成偏振图像的光学系统，用于检测经过光学系统的光的探测器，与光学系统配合且用
