Experimental results. (a) The resulting absorption spectra from the two layer phantom constructs [dashed and dotted spectra indicate the layer-specific absorption (i.e., 100% concentration)] , (b) The resulting reduced scattering spectra from the two layer phantom constructs (dashed and dotted spectra indicate the layer specific reduced scattering). (c) The calculated optical penetration depth based off of the wavelength specific determined absorption and reduced scattering values.
