Paper Abstract

The dependence of the optical density of a model strongly scattering medium-aqueous milk solution on its layer thickness was investigated. IR lasers generating pulses of various short (from nanosecond to femtosecond) duration were used as the radiation sources. There were determined the dependences of the attenuation coefficients of such pulses on the solution concentration in the areas of low and more high optical densities of the solution layer for different values of radiation detector angular aperture. A modification of the two-flux Kubelka-Munk model was used to derive an expression describing the dependence of the transmission of a solution layer on its parameters when radiation detectors with a finite angular aperture are used. The absorption and scattering coefficients of the medium were obtained. A comparison of the calculations and experiments revealed a forward scattering anisotropy of short-duration laser radiation in an aqueous milk solution characteristic for the Mie's scattering.
