Abstract

Système de vérification par ultrasons d'une structure immergée à une certaine profondeur. Il comprend un dispositif destiné à émettre des salves d'ondes sonores à haute fréquence de manière qu'elles traversent une surface de la structure immergée. Un dispositif détecte les réflexions de ces ondes sonores. Un autre dispositif forme une image visuelle montrant les réflexions détectées, et un dispositif affiche cette image à proximité du dispositif d'émission et de détection des ondes sonores. Domaine d'application : contrôle et essai de structures sous-marines.
