technical field [0001] The invention belongs to the field of imaging detection, in particular to a method for measuring the scattering effect of haze particles based on polarization detection. Background technique [0002] Due to the continuous expansion of cities and the rapid development of industry, the economic and social activities of high-density population will inevitably emit a large amount of fine particles. Once the emission exceeds the ability and tolerance of the purification cycle of the atmosphere itself, the concentration of fine particles will continue to increase and accumulate. , coupled with the influence of atmospheric pressure, temperature and other climate conditions, it is particularly easy to cause large-scale haze weather. This kind of haze particles formed by the mutual wrapping of dust and water reduces the accuracy of the detection system and affects the contrast of the imaging system. [0003] Creates a low-contrast environment. Compared with vi...
