Monte Carlo simulation for diffuse backscattering of polarized light from poly-disperse highly dense media
多分散高浓度介质偏振光后向扩散散射的Monte Carlo仿真

A Monte Carlo simulation model for the diffuse backscattering of the polarized light from the poly-disperse highly dense media is developed and the effective free pathlength distribution function of the poly-disperse system is given. Simulation is conducted for the mono-disperse polystyrene suspensions with particle sizes of radii 50 and 550nm, and poly-disperse suspensions containing the above two particles with the volume fraction ratios of 4:1, 1:1 and 1:4. The relation between the spatial intensity variations of the light diffuse backscattering pattern and the volume fraction ratio of the poly-disperse suspensions is analyzed qualitatively.
