(a) Diffuse reflectance spectrum [ ${\mu }_{\text{s}}^{\prime }({\lambda }_0)=2.49{\text{mm}}^{-1}$ and [Hb] = 2 mg/ml] and the LUT-fit from a tissue phantom (validation set). Scatter plot of the known versus measured values of (b) and ${\mu }_{\text{s}}^{\prime }(\lambda )$ and (c) μ_a(λ) for all tissue phantoms. The solid line indicates perfect agreement.
