Understanding light propagation in biological tissues has practical applications to medical imaging, diagnosis and monitoring. The radiative transport equation governs light propagation in tissues. It takes into account scattering and absorption due to inhomogeneities in the medium. One important area of tissue optics research is obstacle scattering. Understanding obstacle scattering in tissues is a key step towards developing methods to locate and classify anomalies such as tumors. In this talk we discuss the problem in which the obstacle is a thin absorbing plate. Throughout the discussion of this problem, we draw several analogies to the classical theory of diffraction.
