Light transport model of frequency domain in a n-layered mismatched tissue

Light transport model has great potential in medical diagnosis and therapy because of the non-invasive nature of light and the selectively poisonous effect to tumors of photodynamic treatment Light transport model must be understudied for basic research and clinical application of biomedical optics., many investigators only study the diffusion equation of matched medium, they take the tissue as the same refractive index. In fact, A tissue is multi-layered mismatched medium, In order to understand the light transport in tissue,The frequency domain analytical solutions of the diffusion equation for photon migration through highly scattering a n-layered mismatched medium have been obtained. The effect of the refractive-index mismatch is taken into account, and the extrapolated boundary condition has been considered. At the same time, the phase in different situation is calculate use the model.
