METHOD AND SYSTEM FOR NON-DESTRUCTIVE TESTING

摘要

A testing system with a control unit (10) connected to a plurality of sending and or receiving transducers (5, 6). In combination, the control unit (10) and transducers (5, 6) are arranged to receive a current signal originating from the sample, to calculate a fidelity index ? by correlating a tail part of the current signal with a reference signal, and to compare the fidelity index ? with a threshold value ?thr
