Abstract
A quantitative assessment of effects due to the interference of waves scattered by an ensemble of particles is given. It is shown that in the propagation of a collimated beam of light in a turbid medium, interference effects give rise to an additional stretching of the scattering indicatrix for a particle system, as compared with the scattering indicatrix for a single particle. The interference “tongue” obtained is concentrated in a very small angle in the direction of the light beam incident on the particle system. (Over a wide range of experimental conditions this angle is of the order of a few minutes.)
Formulas are obtained for the instrumental scattering coefficient in the case of light scattering by volumes in the form of a sphere, disk, or rod. The analytical form of the formulas obtained indicates the possibility of concentration effects in experiments in a turbid medium.
