Anisotropic absorption and reduced scattering spectra of chicken breast tissue measured using oblique incidence reflectometry


Oblique incidence reflectometry is a simple and accurate method for measuring the absorption and reduced scattering coefficients of turbid media. We used this technique to deduce absorption and reduced scattering spectra form wavelength-resolved measurements of the relative diffuse reflectance profile of white light as a function of source- detector distance. In this study we measured the absorption and reduced scattering coefficients of chicken breast tissue in the visible range with the oblique incidence probe oriented at 0 to 90 degrees relative to the muscle fibers. We found that the deduced optical properties varied with the probe orientation. This experiment demonstrated the application of oblique-incidence, fiber-optic reflectometry to measurements on biological tissues and the effect of tissue structural anisotropy on optical properties.
