Abstract
We study the propagation of light through a medium containing isotropic scattering and absorption centers. With a Monte Carlo simulation serving as the benchmark solution to the radiative transfer problem of light propagating through a turbid slab, we compare the transmission and reflection density computed from the telegrapher’s equation, the diffusion equation, and multiple-flux theories such as the Kubelka–Munk and four-flux theories. Results are presented for both normally incident light and diffusely incident light. We find that we can always obtain very good results from the telegrapher’s equation provided that two parameters that appear in the solution are set appropriately. We also find an interesting connection between certain solutions of the telegrapher’s equation and solutions of the Kubelka–Munk and four-flux theories with a small modification to how the phenomenological parameters in those theories are traditionally related to the optical scattering and absorption coefficients of the slab. Finally, we briefly explore how well the theories can be extended to the case of anisotropic scattering by multiplying the scattering coefficient by a simple correction factor.

- In the earliest two papers of Yang et al. [Refs. ], the authors make it clear that μ should be greater than or equal to 1, as we assume here, since μ physically corresponds to the factor of increase in the path length due to the scattering. In their later two papers [Refs. ], however, they are unclear on this point and, in fact, seem to implicitly assume that limits in which μ<1 are sensible to discuss. If we do not assume μ must be greater or equal to 1 but instead use the expression shown for s^{2}>/=a^{2}+as over the entire range of ad, it does significantly affect the quantitative results that we obtain for the transmission density for the RKM theory in Section . However, it does not change our basic conclusions concerning the quality of the agreement between the RKM theory and the Monte Carlo results.
- To verify the correctness of the Monte Carlo results, we have made comparisons between two different codes written independently by the two authors in different programming languages using different random number generators. Furthermore, the Monte Carlo results for no scattering (i.e., the rightmost data point in each figure) are found to be in excellent agreement with the exact results that can readily be calculated for that simpler case.
