Paper Abstract

In the present paper, we consider that a planar laser pulse falls obliquely on the surface of a stratified tissue slab. The Green function approach is developed to reconstruct two optical parameters of the stratified tissue simultaneously. By analyzing the strucutre of the fundamental solution, the transport equation of the Green function and the explicit form of the initial condition are derived. The initial condition of Green function is found that correlates to the parameters of tissue and incident angle. By the characteristic method, the measurable boundary data are propagated to the initial value layer by layer for each incident angle. The scattering and absorption coefficient of tissue are then reconstructed simultaneously layer by layer using the explicit expression of the initial condition of Green fucntion. A detailed algorithm for the reconstruction is presented and an imaging picture as a numerical examples is given.
