Figure 2
Plots of melanin concentration versus various depolarization metrics. The degree of polarization (a,b), the entropy calculated from the cumulative Jones matrix (c,d), the entropy calculated from the local Jones matrix (e,f), and some selected metrics (g,h) are shown. In all plots, the melanin concentration is shown with logarithmic scale. The plots of the left and right columns have linear and logarithmic vertical scales, respectively. Third-order polynomial fitting was applied to all the plots except for \(H_{{\text{C}}\_{\text{NBC}}}\), \({\overline{H}}_{{\text{C}}\_{\text{NBC}}}\), \(H_{{\text{L}}\_{\text{NBC}}}\) and \({\overline{H}}_{{\text{L}}\_{\text{NBC}}}\).
