Abstract

For understanding the correlations between temporal and spatial photon distributions in the process of random scattering in turbid media, the Monte Carlo algorithm is used to describe various optical gating conditions. We study the distributions of transmitted photon with time-, aperture-, and angle-gating techniques. We record the optical paths of transmitted photons with different aperture sizes and angles. Time-resolved profiles and polarization states of transmitted photons are also discussed.
