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

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 on imaging are reviewed. © 2009 Wiley Periodicals, Inc.
