Light-transmittance predictions under multiple-light-scattering conditions I Direct problem: hybrid-method approximation

Abstract
Our aim is to present a method of predicting light transmittances through dense three-dimensional layered media. A hybrid method is introduced as a combination of the four-flux method with coefficients predicted from a Monte Carlo statistical model to take into account the actual three-dimensional geometry of the problem under study. We present the principles of the hybrid method, some exemplifying results of numerical simulations, and their comparison with results obtained from Bouguer–Lambert–Beer law and from Monte Carlo simulations.
