Subsurface imaging FDTD - based simulations and alternative scan / processing approaches

Abstract

Nondestructive and noncontacting subsurface imaging is discussed. A finite-difference time-domain (FDTD) based virtual tool is developed to create various imaging scenarios and to generate synthetic scattering data. Matlab-based imaging algorithms are developed to process recorded FDTD data and to reconstruct objects. Different contour synthetic aperture type scanning configurations and reconstruction techniques are applied and their effects oil imaging are reviewed.
