On the basis of the indicatrix of scattering of the particles were calculated spectral characteristics of anisotropy factor for spherical particles with different diameters. The mathematical model of a single layer of a suspension of particles of an inhomogeneous biological medium connects its biophysical and structural parameters and the spectral characteristics of coefficient of diffuse reflection or directional transmission. After conducting multispectral measurements, biophysical and structural parameters are required to be measured indirectly using the regression equation system.
