Simulation Study of Polarization Imaging Model for Mie Scattering Turbid Water Bodies
Based on fused geometric optical imaging, this thesis proposes a theoretical analysis method considering single Mie scattering theory and the Monte Carlo method to study the influence of turbid water on imaging quality. The proposed method analyzes the imaging characteristics of a point light source with different wavelengths (456 nm, 524 nm, and 620 nm) is transmitted through a turbid water environment with different particle sizes and concentrations. The results show that the point light source with wavelength of 456 nm exhibits the best imaging effect when subjected to polarization imaging transmission in the same water environment and nonscattering environment. In addition, when the 456-nm light passes through turbid water with scattering particle sizes of 1 μm and 2 μm, the imaging effect of linear polarized light is better than that of circular polarized light, which is better than natural light. However, while passing through turbid water with particle sizes of 3 μm, 4 μm, and 5 μm, the natural light and linearly polarized light exhibit the best and the worst imaging effects, respectively. Overall, this paper provides new ideas and methods for underwater polarization imaging technology.
