Abstract

Dispositif de contrôle non destructif d’une structure, comprenant un premier transducteur (E) apte à générer une onde ultrasonore principale se propageant dans la structure, un second transducteur (R) apte à capter l’onde ultrasonore principale après sa propagation dans la structure et à la convertir en signal électrique principal et un capteur de bruit (E), le capteur de bruit (E) et le second transducteur (R) étant aptes à capter un ou plusieurs signaux perturbateurs électromagnétiques et à les convertir en un signal électrique secondaire, le dispositif comprenant un module d’acquisition configuré pour mesurer, sur une même fenêtre temporelle d’acquisition, les signaux captés par le capteur de bruit (E) et par le second transducteur (R), et un organe de réduction de bruit (ORG) connecté au capteur de bruit (E) et au second transducteur (R) et configuré pour soustraire le signal électrique secondaire mesuré par le capteur de bruit au signal électrique principal mesuré par le second transducteur.
