Abstract: This talk will outline the mathematical framework for
tomographic imaging of structural damage. Tomographic imaging requires the
use of arrays of actuators and sensors, so as to provide a multiple view
of the damaged region. When using ultrasonic waves for imaging, one cannot
ignore the effects of scattering and diffraction, unlike the case for
conventional (X-ray) tomography. The appropriate mathematical framework is
that of diffraction tomography. The talk will outline the mathematical
basis for diffraction tomography, as well as indicating the current state
of progress with applying that approach for in-situ imaging of damage, and
some of the significant challenges that remain for an effective
application of that approach.
