Abstract

A three-dimensional Monte Carlo simulation of transient radiative transfer is performed for short pulse laser transport in scattering and absorbing media. Experimental results of a 60 ps pulse laser transmission in scattering media are presented and compared with simulation. Good agreement between the Monte Carlo simulation and experimental measurement is found. The refractive index of the scattering particles is found to influence strongly the prediction of transmitted pulse shape. The temporal shape of the transmittance is very weakly influenced by the output detector angle for a diffuse medium. Scaled isotropic scattering modeling is shown to be insufficient in transient three-dimensional radiative transfer for early times.
