Abstract:

The depth behavior of light scattering in turbid media with slowly decreasing phase functions (i.e., when the scattering probability decreases with increasing scattering angle γ more slowly than γ^-4) is studied. The Fokker–Planck approximation is not used. Postulating the angular spectrum shape in the depth regime we have proposed and realized a regular algorithm for determining the spectrum parameters. The depth variance and extinction coefficient are described analytically. The results of our study are in good agreement with numerical data and in limiting case they coincide with the results of the diffusion approach.
