heal.abstract	In this study a rigorous approach to tissue fluorescence is presented, based on the study of tissue fluorescence as an electromagnetic scattering problem. Fluorescence scattered wave is treated by taking a continuous spectrum distribution in a region of frequencies lower and equal to the excitation frequency. The existence of inelastic field components can be considered as a result of the particular form, that the polarization of the irradiated medium has. In order to provide the most general formulation, the polarization vector P for the observed light frequency ω can be written as P(r,ω) = ∫ω oω dω'E(r,ω')τ (ω,ω'), where E(r,ω') is the electric field at the excitation frequency ω' and (tau) (ω,ω') the transfer permittivity function from ω' at the spatial point r, to the emission frequency ω , measured at the same point. Substitution of the polarization vector into the electromagnetic field equations leads to a formulation of the inelastic field components. The model used is based on considering tissue as a single dielectric layer, under pulse excitation. The theoretical background for such an evaluation, together with the mathematical technique used and the theoretical results, are presented. ©2004 Copyright SPIE - The International Society for Optical Engineering.	en
