The pulsed ultrasonic polar scan (P-UPS) technique provides a map with characteristic
contours reflecting the critical bulk wave angles, which directly relate to the in-plane elastic
properties of the insonified material spot. Besides these contours, additional information is
captured in a P-UPS experiment which has particular importance for the inspection of
anisotropic materials. By extensive post-processing on a single P-UPS experiment, we
successfully extracted the local directional (i) critical bulk wave angles,(ii) phase velocity …
