摘要

Abstract: The effects of discrete absorbing and scattering objects on light propagation characteristics in random media were examined. Light propagation in the inhomogeneous medium was modeled using a finite difference representation of the time-dependent diffusion equation. Time-resolved experiments were conducted in brain- simulating phantoms containing objects of various sizes and optical properties. The validity of the model was assessed by comparing the experimental pulse to that predicted by the model. !19
