Paper Abstract

A connection is established between the degree of surface roughness and the diffuse maximum of light scattering indicatrix in the direction of mirror reflection. It is proposed to consider its mean contribution, p, to the total scattered intensity as the quantitative measure of the surface roughness degree. It is shown that the effective mirror constituent p determines the character of light transfer in the space, bounded by the rough reflecting surface, and must be allowed for when calculating relevant optical devices, e.g. scintillation detectors. For that purpose, a constructive calculation method was developed and verified by the quantitative comparison with experimental data on spectrometric characteristics of scintillation crystals. The surface roughness parameter p dictates the character of their dependence on geometric and optic parameters of a crystal.
