摘要

Considering propagation of radiation through light-scattering layers (such as paints, photomaterials, foils, skin etc.), one usually finds out the total energy absorbed by the layer using any experimental, analytical or computational methods. It is insufficient for solving of some practical problems. It is important to know the distribution of the absorbed energy among disperse layer components, i.e. among a disperse phase and a bulk.The method is proposed for estimation of quantity of absorbed energy and its deep distribution separately for each structure component of the layer, i.e. for particles and a bulk. The computational results are given for a layer with the following parameters: a mean size of light-scattering particles, d=0.3 mcm; size distribution of particles is logarithmically normal one with polydispersity, C_v=20 %; volume concentration of particles, V_c=5, 7.5, 10 and 15%; thickness of the layer, H=10 mcm. Computations were performed for wavelength λ=442 nm.
