Experimental assessment of turbid medium optical properties using the fast-sweep concept. (a) Measurement diagram with a human hair as absorbing target immersed in a turbid medium (intralipid solution of different concentrations as indicated in top right corners of panels). Optical properties (reduced scattering coefficient ${\mu }_s^{\text{'}}$ and effective attenuation coefficient ${\mu }_{eff}$) of the medium were determined using Model I (orange) and Model II (blue - ${\mu }_{eff}$ only). The point and error bar indicate estimation mean and standard deviation. A total of 8 samples (8 datasets) were used for statistics. The dotted line (${\mu }_{eff}$) and the shaded region between dotted lines (${\mu }_s^{\text{'}}$) indicate the estimated value and range, respectively, for the results of Ref. [24].
