Abstract
An overview is given describing the physical basis of ultrasonic reflectivity as it relates to solid material characterization. The examples given illustrate critical angle reflection, Rayleigh and Lamb waves, and crystal orientation via reflection measurements.
Résumé
On donne dans l'article un panorama des principes physiques de base concernant la réflectivité ultrasonore en relation avec la caractérisation de matériaux solides. Les exemples donnés se rapportent à la réflexion critique, aux ondes de Rayleigh et de Lamb et à l'orientation cristalline effectuée au moyen de mesures de reflexion.
