Abstract

We compare two methods for the optical characterization of turbid media. The estimates of the absorption and reduced scattering coefficients (μa and μs) by a spatially resolved method and a time-resolved method are performed on tissue-like phantoms. Aqueous suspension of microspheres and Intralipid are used as scattering media with the addition of ink as an absorber. μs is first measured on weakly absorbing media. The robustness of these measurements is then tested with respect to a variation of μa. The spatially resolved method gave more accurate estimates for μs whereas the time-resolved method gave better results for μa estimates.
