| Summary: | The non-destructive evaluation of defects by automatic procedures is of great importance for
structural components. Thanks to the developments of the non-contact ultrasonic techniques, the automation
of the inspections is gaining a progressively important role. In this work, an automatic inspection technique for
the evaluation of defects by the analysis of B-scan images obtained by a laser ultrasonic system is presented. The
data are extracted directly from a B-scan map obtained for a panel with internal defects, and are used to build an
image of the cross section of the panel. The proposed automatic procedure allows the definition of size,
position and shape of defects in panels of known thickness |
