Autoquenching of spherical photon density waves during propagation in a turbid medium.

The effect of the formation of deep minima in frequency characteristics of photon density waves (PDWs) during their propagation in scattering media with different optical characteristics has been studied by statistical Monte Carlo modeling. The simulation was performed for the Henyey-Greenstein scattering phase function with the anisotropy factor value varying in the range of 0-0.93. The dependence of the position and magnitude of the minimum in the frequency response of PDWs on the combination of the parameters of the scattering medium and the distance to the radiation source is demonstrated.
