Photon-density waves in the time and frequency representations

Resumo

The Monte Carlo simulation of the diffusion of photons in the time and frequency representation has been performed with the Bethe–Salpeter equation for the description of radiation transport. The histogram of a backscattered ultrashort pulse in the time representation in the region of the parameters typical for bio tissues, as well as the parameters of diffuse photon density waves in the frequency representation, has been calculated within the developed approach. The results are in agreement with the previous experimental data. The dependence of the time histogram on the anisotropy of the phase function has been calculated.
