To study the general traveling properties of polarized light in the scattering medium with the influence of multi-factors, the influence of wavelength, medium thickness, particle parameters and incident polarization state on transmission properties of polarized photons is analyzed systematically. The Monte Carlo method is adapted to track polarization state changes of each photon, and the Stokes vector and polarization information after multiple scattering are obtained through statistical analysis of the polarization curve, and the traveling rules of polarized light in scattering medium are analyzed. Simulation results show that the particles with relative larger scale parameter have smaller changes on the incident light polarization state. Linear polarization light is good at keeping the polarization state. Circular polarization light can restore the polarization state in a short time. The larger the particle radius is, the stronger the recovering ability is, and the direction of rotation of the electric vector changes during the process of transmission.
