Description

technical field [0001] The invention belongs to the field of polarization spectrum detection, in particular to a polarization spectrum laser detection method in haze environment. Background technique [0002] Due to the low contrast caused by the haze environment, ordinary intensity imaging cannot accurately obtain target information, military identification and detection, and traffic safety are all greatly affected. At this time, compared with traditional imaging techniques (intensity imaging, spectral imaging), due to polarization On the basis of intensity imaging, imaging adds polarization dimension information that cannot be reflected by intensity and spectrum, which can significantly enhance the difference between the target and the background, and increase the operating distance in environments such as haze and smoke, thus becoming an effective means to solve the above problems. [0003] In order to solve the imaging problem in the haze environment, it is necessary to ...
