Abstract

Dispositif de contrôle non destructif et non pénétrant d'un objet au moyen d'un faisceau d'ondes ultrasoniques engendrées par un transducteur 12 transmis à travers un milieu de transmission liquide et réfléchi sur un réflecteur 13 en direction de l'objet à contrôler. Afin de réduire ou de supprimer les signaux parasites, le miroir est pivoté de manière que l'angle incident du faisceau transmis par le transducteur 12 sur le miroir 13 soit toujours supérieur à l'angle d'excitation d'ondes superficielles à l'interface de la surface du réflecteur 13 et du milieu de transmission. Application à des diagnostics médicaux.
