Abstract: We present the optical characteristics of the mucosa and submucosa of human colon tissue. The experiments are performed in vitro using a LAMBDA 950 spectrophotometer in the 350 – 2500 nm spectral range. The absorption and scattering coefficients and the scattering anisotropy factor are calculated based on the measured diffuse reflectance and total and collimated transmittance spectra using the inverse Monte Carlo method.

Keywords: integrating sphere spectrophotometry, inverse Monte Carlo method, mucous membrane, submucous membrane, absorption coefficient, scattering coefficient, reduced scattering coefficient, scattering anisotropy factor.
