L'objectif premier des ondes guidées par interface dans la microscopie acoustique est d'améliorer le contraste, c'est-à-dire augmenter la sensibilité de la réponse correspondent aux propriétés du matériel et d'adhésion à l'étude. Deux nouvelles techniques basées sur les propriétés uniques des ondes guidées sont proposées pour maximiser la détection des imperfections situées aux limites pour les cas d'interfaces ayant une orientation normale ou transverse.The primary role of guided interface waves in acoustic microscopy is to enhance the contrast, i.e. to increase the sensitivity to material and bond properties. Two novel techniques based on the unique features of guided waves are suggested to maximize the detectability of boundary imperfect...
