Abstract

An experimental set-up is presented for wavelength and spatially resolved reflectance measurements (SRR) via optical fibers and imaging optics. In order to characterize the set-up, we made a set of silicone rubber phantoms with different absorber and scatterer concentrations. The remission profiles gained from the phantoms are the input for a look-up table (LUT) based "inverse Monte-Carlo simulation" to deduce absorption μ_a and reduced scattering coefficients μ_s'. As an independent method for determination of μ_a and μ_s' we also made measurements with an 'integrating sphere spectrometer' (ISS). Our normalization procedure of the SRR measurements is presented and the validity of this method is discussed.
