Abstract
Traditional Monte Carlo method lacks the capability to trace and record polarization and phase information when simulating the transmission of photons. In this paper, based on Mie scattering theory and Electric Field Monte Carlo(EMC) method, we simulates the multiple scattering between photons and smoke particles and obtains the intensity and electric field information of backscattered photons, by calculating the rotation rules of local coordinate system and amplitude scattering matrix of photon. Simulations reveal that with an idealized point light source, backscattered photons concentrate into a speckle on the receiving surface, which expands as the scattering media thickens. The number of backscattered photons rapidly decreases over time, while their degree of polarization stabilizes within a specific range, forming a cross pattern that rotates based on the light's initial polarization. These findings offer valuable insights for developing anti-smoke interference imaging techniques.
