Description

Technical field [0001] The present invention belongs to the field of photoelectric detection, and more particularly to an off-axis three-reverse full-spectrum segment polarization spectrum imaging detection device. Background technique [0002] Due to the smog, the shadowing effect of the smog is to reduce the visibility of light, so that roads and civil aviation traffic are blocked, and it has adversely affects the national economy. The existing photoelectric imaging detection system is more intensity system, but with the increasing haze weather, only the performance of the optoelectronic system performance of intensity imaging technology is limited. [0003] In 2018, the Chinese Academy of Sciences Anhui Optical Precision Mechanical Institute proposed a method of scaling a splitting amplitude while simultaneous polarization imaging instrument using a standard line polarization light source and a circularly polarized light source. The first three columns of the linear polarizati...
