摘要: A photon migration model is applied to the analysis of remote-sensing techniques that use light probe properties biological tissues. Specific consideration given effect path length on signals obtained from laser Doppler detection blood flow in tissue microvasculature. We show how changes volume or variation spacing between delivery and detecting fibers might affect measurements. also examine can parameters determined by time resolved optical spectroscopy oxygenation. Anisotropies angular distribution scattered photons are taken into account.
