A Random Walk Theory of Time-Resolved Optical Absorption Spectroscopy in Tissue

A random walk theory of photon diffusion in tissue is discussed, and shown to reproduce features of some recent experiments by Chance et al. The theory allows one to calculate, from the absorption and scattering coefficients of turbid medium, the time dependence of surface emission.
