Figure 6.

An example of fitting quality of the measured parameters. [A] The values of ln(AC.ρ²) as a function of source-detector distances (ρ) are presented by circles. Different colors correspond to different wavelengths (color-mapped in the legend) and the dashed lines are the corresponding linear fit. [B] Phase shift (radian) as a function of distance at the 8 wavelengths. [C] The circles are the measured absorption coefficients (μ_a) at 8 wavelengths; the blue line is the fitted absorption spectra of oxy- and deoxy-hemoglobin. [D] The circles are the reduced scattering coefficients (${\mu }_s\mathrm{\prime }$) at the 8 wavelengths and the blue line is the fitted scattering model. [E] The measured intensity autocorrelation function (red) measured with DCS and the fitted theoretical model (blue).
