Abstract
A method of measuring in vivo skin tissue thickness employs noninvasive NIR absorbance spectra. Constituents of a tissue sample are characterized and quantified based on differing absorbance spectra and scattering properties, allowing thickness and chemical composition of layers to be estimated. Pathlength normalization reduces spectral interference in predicting analyte concentrations.
