Titel
Holographic reconstruction by backpropagation of defect images obtained by scanning laser acoustic microscopy
Abstract
Scanning Laser Acoustic Microscope (SLAM) images which are acoustic holograms can be improved by backpropagation in the Fourier domain of the displacement field measured at the surface of the sample. We applied this technique to delineate the size of defects in advanced ceramics.
