Calculation of light fields of concentrated sources in turbid media with strongly anisotropic scattering

An efficient approach to solving the equation of radiation transfer in a turbid medium with strongly anisotropic scattering is proposed based on the small-angle approximation of the theory of radiation transfer with allowance for the dispersion of the radiation propagation path length, as well as with allowance for polarization. The approach is applied to the solution of the problem of the field of a pointlike isotropic radiation source in a two-dimensional medium.
