Fig. 2.

Representative samples of the normal and benign tissues (left column) and malignant tissues (right column). Panes are color-coded by tissue subtype. Solid boarders denote planar, diffuse illumination ($f_x=0.00{\mathrm{mm}}^{-1}$, $\lambda =490\mathrm{nm}$) reflectance. Dashed boarders denote subdiffuse illumination ($f_x=1.37{\mathrm{mm}}^{-1}$, $\lambda =490\mathrm{nm}$) reflectance. Scalebar is shown in the bottom-right corner.
