Abstract

Scalar diffraction theory is used to model the propagation of diffuse photon density waves in heavily scattering media. The principal difference between this and previous approaches is that the three classical boundary conditions have been considered. The model is shown to qualitatively demonstrate the correct trends for diffraction by planar objects embedded at different depths within the scattering medium. Quantitatively the three scalar diffraction boundary conditions are shown to provide different results in both amplitude and phase of the diffraction pattern at the detector plane. Preliminary results indicate that the Kirchoff boundary condition provides the best match to Monte Carlo simulations.
