(a) and (b) Physical parameters extracted from the LUT inverse model ( ${\mu }_{\text{s}}^{\prime }({\lambda }_0)=0.91{\text{mm}}^{-1}$ (□), 1.83 mm⁻¹ (○) and 2.75 mm⁻¹ (◇)). The solid line indicates perfect agreement. Error bars for these measurements were too small to show (<2%). (c) In vivo reflectance spectra from two representative groups: clinically normal and BCC. The thin solid line indicates the model fit.
