摘要

A detailed investigation of the use of time-resolved trasmittance for the optical characterization of scattering media by use of different analytical solutions to the diffusion equation has been performed. A femtesecond Ti:sapphire laser working at 800 nm and a streak camera with a time resolution of a few picoseconds were employed. Different latex and Intralipid solutions as well as biological samples were investigated. Reduced scattering coefficients were evaluated, and good agreement with the Mie predictions was found. An estimation of the order of magnitude of the absorption coefficient was obtained for the low-absorbance samples examined. These studies confirm experimentally that time-resolved tras-mittance can be employed usefully for evaluating μ_(s)' values of thick scattering samples when a proper theoretical description that takes into account realistic boundary conditions is used.
