Abstract
Nowadays, haze environment has a severe impact on astronomical ground-based space observations, which leads to the decline of imaging quality radically. In this article, the impact on the ground station caused by haze environment has been analyzed. In order to improve the imaging quality of the observation target, an optical system has been designed using perspective polarization imaging techniques. To ensure the precision of polarizing measurement and quality of wide field imaging, We analyzed the design of the polarizing of the objective lens and the difficulties of the structure of the system. Finally we have designed a reversed telephoto telemetric structure in the image space successfully. Improved entrance light and achieved the performance indicators to the field of 44.3 °, f # 4, back focal length 2 times the focal length, focal length 20mm. The experiments of the system proved to be successfully improved the imaging quality compared with the traditional imaging system.
