Study on the Polarized Light Transmission Characteristics Under Complex Sea Fog Environment

Aiming at the polarized light transmission characteristics under complex sea fog environment, the sea fog is divided into two layers of salt fog layer and water fog layer. Firstly, the simulation model of the corresponding layer is established based on Monte Carlo and T-matrix method, and the scattering characteristics of the particles between the two layers are linked by the multiple addition cumulative method; secondly, an indoor semi-physical simulation experiment platform was built to explore the effects of different optical thickness, incident wavelengths and polarization states on the transmission characteristics of polarized light; finally, the simulation and experimental results are compared and analyzed. The results show that when the incident light has a longer wavelength, it decreases more slowly, i.e. polarized light with a longer wavelength retains more polarization information after transmission; linearly polarized light decreases faster compared to circularly polarized light, i.e., circularly polarized light has better polarization preservation. This study provides a theoretical basis for the study of polarized light transmission characteristics under complex sea fog systems.
