Abstract
Some applications of laser-generated convergent acoustic waves to the detection of surface-open cracks are described. The converging wave is thermoelastically generated by an axicon-focused laser beam and detected at the center of convergence by an interferometric probe. A multi-radius technique for crack localisation is presented.
