Abstract

Procédé pour explorer par faisceau ultrasonore focalisé un segment C' situé dans un second milieu, le faisceau ultrasonore étant créé par un traducteur focalisant disposé dans un premier milieu, lesdits premier et second milieux étant séparés par une surface de séparation. Ce procédé se caractérise en ce que pour déplacer un point de focalisation du faisceau ultrasonore dans le second milieu et explorer ledit segment C', on translate le foyer du traducteur le long d'un segment de courbe C, image optique du segment C' dans ladite surface de séparation. Application à la vérification de soudures.
