Light propagation at interfaces of biological media: boundary conditions.
Methods of biomedical optics employed to study and characterize biological media involve measuring light diffusely transmitted though tissue. In this paper we describe boundary conditions for the propagation of light at interfaces of biological media. Boundary conditions are derived for a generalized radiative transfer model that accounts for the propagation of light in biological media with a spatially varying refractive index and includes the effects of ray divergence. This work will improve the accuracy of the measurements in biomedical optics techniques and will enhance our understanding of tissue physiology.
