Polarization Detection Performance of Directional Polarimetric Camera
Bihai Tu, Jin Hong, Pingping Yao, Binhuan Meng, Yinlin Yuan, Miaomiao Zhang, and Jianwen Weng
Directional polarimetric camera (DPC) is used to monitor several parameters related to the global atmospheric aerosol and clouds as it can detect atmospheric multi-angle polarization. However, it is an ultra-wide-angle optical instrument; therefore, the polarization effect of lens cannot be neglected, and it should be

Satellite Signature Effects Based on the Retroreflector Uneven Distribution Model
Bowen Guan, Ning An, Cunbo Fan, Chengzhi Liu, Guanyu Wen, Jian Gao, Haitao Zhang, and Shuzhuo Miao
The millimeter accuracy of a satellite laser ranging (SLR) system is often hindered by the satellite signature effects. Based on the actual distribution of the satellite retroreflectors, the retroreflector uneven distribution (RUD) model is proposed in this study. The relationships between laser incident angles and the
