We compare two methods for the optical characterization of turbid media. The estimates of the absorption and reduced scattering coefficients (mu(a) and mu(')(s)) 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. mu(')(s) is first measured on weakly absorbing media. The robustness of these measurements is then tested with respect to a variation of mu(a). The spatially resolved method gave more accurate estimates for mu(')(s) whereas the time-resolved method gave better results for mu(a) estimates.
我们比较了两种用于浑浊介质光学特性表征的方法。通过空间分辨方法和时间分辨方法对类组织体模进行吸收系数和约化散射系数（μ(a) 和 μ'(s)）的估计。微球水悬浮液和英脱利匹特用作散射介质，并添加墨水作为吸收剂。首先在弱吸收介质上测量 μ'(s)。然后针对 μ(a) 的变化测试这些测量的稳健性。空间分辨方法对 μ'(s) 的估计更准确，而时间分辨方法对 μ(a) 的估计结果更好。
