Summary:
Due to the space limitation of the current paper it is not possible to carry out a more detailed analysis of, for example, the influence of 3D-stochasticity of the scattering medium on the transfer of optical radiation. But even the abovementioned calculation results for a simple enough model show that taking stochasticity into account gives an increase of the probability of passage. The ratio of the probability of passage in a stochastical medium to the probability of passage in a determinate medium grows with the increase of optical thickness. The obtained numerical results demonstrate that, when interpreting physical changes of radiation fields in a cloudy medium in some cases the stochastical properties of the medium play a significant role. The weight algorithm considered in this paper allows avoiding the laborious procedure of modeling random photon trajectories in randomly-inhomogeneous scattering media and therefore reducing the calculation time. Realization of the algorithm is quite simple. The profit in terms of calculation time depends upon the choice of model for the random field.
