Abstract

L'invention concerne le sondage non destructif par ultrasons par la méthode des échos récurrents. Une au moins des caractéristiques qui déterminent la sensibilité de détection, puissance ou fréquence d'émission, gain des amplificateurs, etc., est modifiée de façon cyclique discontinue d'un cycle de récurrence à un autre, de façon à donner cycliquement à l'ensemble de la chaîne une sensibilité différente, ce qui permet de mettre en évidence et de comparer des échos necessitant des sensibilités de détection différentes.
