A fully automated system for time-resolved reflectance spectroscopy in the wavelength range 610-1010 nm was effectively used to measure the absorption and transport scattering spectra from a two-layer diffusive medium with differences in the absorbing properties. The measured transport scattering spectra at different inter-fibers distances are not influenced by the distinct absorption of the two layers. The measured absorption spectra show a non linear behavior that is strongly dependent on the inter-fiber distance. An algorithm was developed and preliminary applied to reconstruct the absorption spectra of the two layers by exploiting the information obtained from measurements at different inter-fiber distances.

Abstract

A fully automated system for time-resolved reflectance spectroscopy in the wavelength range 610-1010 nm was effectively used to measure the absorption and transport scattering spectra from a two-layer diffusive medium with differences in the absorbing properties. The measured transport scattering spectra at different inter-fibers distances are not influenced by the distinct absorption of the two layers. The measured absorption spectra show a non linear behavior that is strongly dependent on the inter-fiber distance. An algorithm was developed and preliminary applied to reconstruct the absorption spectra of the two layers by exploiting the information obtained from measurements at different inter-fiber distances.
