The study of the process of light propagation in random inhomogeneous media leads, as a rule, to the solution of two principal problems. The first one is to find out the optical properties of the medium from the results of detection of scattered field of a certain structure. The second problem is to find out the structure of light field, that propagates through the scattering medium, with the known optical characteristics. These problems are solved usually by spectrometric methods, and the solution is derived either in the form of determining the integral characteristics, or by eliciting the properties of a sought value in a small volume.
