摘要
Phase function is to determine the photon propagation direction change for each scattering step in Monte Carlo simulation. Henyey Greenstein function is widely used in the Monte Carlo program. In this study, we implement 3 different phase functions: Henyey Greenstein, Double Henyey Greenstein and Mie-Theory-Generated phase function. The results show that when light source is collimated beam or focused beam, there is remarkable difference of reflectance flux in the central region of incident light.
