Features of Light Scattering in Turbid Media As Modeled for Two-Component Emulsions

Specific features of the angular distribution of scattering intensity in a two-component turbid medium consisting of spherical particles have been investigated using numerical simulation. The algorithm for calculating multiple scattering in a turbid medium was based on the Monte Carlo method. Laws of change in the shape of light-scattering phase function in dependence of the size and number of particles per unit volume of the medium are revealed. It is shown that, in comparison with the case of single-component medium, addition of a fraction of particles with sizes larger than the main-fraction particles by an order of magnitude leads to deviation of intensity at forward scattering angles (from 0° to ~40°) to smaller values. Simulation was performed for intermediate-size particles of the main and impurity components of the turbid medium, which approximately correspond to the fat phase of milk and cellular impurities, respectively.
