Statistics of light deflection by randomly oriented interfaces in the geometric optics approximation

摘要

The statistics of light deflection by interfaces between two media is analytically related with the angular probability density between the normal to the interface and the incident beam. In the proposed model all reflection and refraction events are considered as independent with statistical weights equal to Fresnel intensity coefficients. The calculus of phase matrixes of light deflection resulting in the interaction with the randomly oriented interface is proposed. The balance of integrated probabilities of reflected and refracted photons from both sides of the interface allowed quantitative estimates of the probability of photons to be situated in different phases of inhomogeneous media.
