Abstract
Fokker-Planck-Eddington approximation can be used to approximate the radiative transport equation when scattering is forward-peaked. In the approach, forward-peaked scattering probability is approximated using delta functions and smoothly varying Legendre polynomials. In this work, the approximation is used to model light propagation in turbid media with low-scattering regions. The proposed model is tested using simulations, and compared with the radiative transport equation, the diffusion approximation, and the coupled radiative transport - diffusion model. The results show that the Fokker-Planck-Eddington approximation describes light propagation with good accuracy. © 2013 OSA-SPIE.
