Abstract

The light propagation in biological tissue having anisotropic optical properties is investigated. Monte Carlo simulations employing the phase function of infinitely long cylindrical scatterers and the Henyey-Greenstein function are performed and compared to spatially-resolved reflectance measurements of semi-infinite turbid media. In addition, simulations are shown for the spatially-resolved reflectance and transmittance from the surfaces of cubic turbid media. It is found that the light propagation in anisotropic turbid media is very different compared to turbid media that have isotropic optical properties. For example, it is observed that the light which is incident perpendicular to the top surface of the cube may be transmitted mainly from a single lateral side.
