Abstract: The paper describes experimental studies of the optical properties of tissues of the stomach wall and liver of the rat.For this purpose an experimental setup based on the integrating sphere was developed and the spectra of total and collimated transmission and diffuse reflectance of biotissues in the spectral range of 300-1100 nm were measured.Using the inverse Adding-Doubling method the spectra of the optical coefficients of absorption, light scattering, reduced scattering and the scattering anisotropy factor were determined.Using the turbidity spectrum method, the spectra of the reduced scattering coefficient were analyzed.According to the results of experimental studies, the features of the spectral dependence of the optical properties of the tissue are revealed depending on the type of organ being tested, potential chromophores are determined, as well as the sizes and concentrations of the dominant scattering centers.
