偏振成像探测技术针对复杂环境中识别探测目标具有明显的优势和广阔的应用前景，偏振大气信道环境下的传输特性尤为重要。采用平行平板间对流形式研制了大气湍流模拟装置，在此基础上，结合激光发射及偏振参数检测装置，对湍流环境中激光偏振传输特性的变化规律进行实验研究，结果表明线偏振光经过大气传输后会出现较明显的退偏现象，而圆偏振光则表现为较弱的退偏现象，且可很好的保持原有旋向继续传输，另外，强湍流比弱湍流对偏振传输影响大。该结果验证了圆偏振光在大气信道中传输保偏性能好。

Polarization imaging detection technology in the complicated environment on the recognition of target detection enjoys obvious advantages and broad prospects. Polarization properties of atmospheric transmission channel environment are particularly important. The parallel plates convection device is adopt to develope simulation of atmospheric turbulence. Based on this, experiments are conducted to study the change regularity of the polarization of laser transmission characteristics under turbulent environment, combined with the laser emission and polarization parameter detection device. The results show that linearly polarized light will appear obvious depolarization phenomenon passing through the atmosphere, but circularly polarized light shows weak depolarization phenomenon, which is very good to maintain the original rotation to continue transmission, and the strong turbulence affects more heavily than weak turbulence on the polarization transmission. The results prove circularly polarized light transmission polarization can maintain good performance in the atmospheric channel.
