In this paper, a new sensor for ultrasonic guided waves (UGW) acquisition is described. It is capable of localized step-by-step signal acquisition making possible defect identification and classification. In addition, the effectiveness of a method for defect classification is investigated. It is based on the evaluation of the angular profiles corresponding to each detected echo. Finally, the method was tested on experimental results. © 2007 IEEE.

Abstract
In this paper, a new sensor for ultrasonic guided waves (UGW) acquisition is described. It is capable of localized step-by-step signal acquisition making possible defect identification and classification. In addition, the effectiveness of a method for defect classification is investigated. It is based on the evaluation of the angular profiles corresponding to each detected echo. Finally, the method was tested on experimental results. © 2007 IEEE.File in questo prodotto:
