Study of multispectral polarization visible light propagation properties under smog conditions

Polarization imaging technology has shown great advantages in military reconnaissance, vegetation remote sensing and aerosol detection, and the study of the properties of the polarized light transmission can better promote the development of technology. In this paper, according to the characteristics of multi-spectral polarized light transmission in smog environment, an experimental test device of multiple spectral bands of visible light is built in the smog simulation environment, experiments show that when the wavelength changes between 0.5–0.73um, the polarized light of the circularly polarized light is larger than that of the linearly polarized light, and the linearly polarized light exhibits better polarization characteristics in the other wavelengths of the visible light.
