NONLINEAR DIFFRACTION TOMOGRAPHY - THE USE OF INVERSE SCATTERING FOR IMAGING

Our recent inverse scattering work has been to derive inverse scatteri ng theory and algorithms that can be used to process practical experim ental data. The theory makes use of computation of the forward scatter ing solution. Therefore, an efficient forward solver is instrumental t o the rapid solution of the inverse scattering problem. The advantage of the more sophisticated theory over a linear theory is that it accou nts for multiple scattering effects within the scatterers which often give rise to distortions in an image. A new method to invert strong sc atterers, such as metallic scatterers, is presented. (C) 1996 John Wil ey & Sons, Inc.
