Light Transport in Tissue |
IntroductionWhen light strikes a boundary, the fraction of light reflected depends on the polarization and angle of incidence of the light as well as the ratio of refraction indices between the two media. The first section of this appendix reviews the basic reflection formulas needed for later calculations in this appendix. The second section discusses multiple internal reflection of radiance in a glass slide. The third section calculates the first three moments of Fresnel reflection. The next few sections give details and tables for various approximations for these moments made by other authors. Finally, the last sections calculate a boundary condition parameter used in the boundary conditions of the diffusion (delta-Eddington) approximation.
