Characterization of periodic or quasi periodic rough surfaces by ultrasonic spectroscopy

Description

The scattering of wide-band ultrasonic pulses from rough surfaces is investigated with an ultrasonic spectroscopy technique. The spectral content of the echo is correlated to the quality of the insonified surface. Some periodic defects can be taken out from random defects

Abstract (French)

La diffusion d'une impulsion ultrasonore large bande par des surfaces rugueuses est etudiee par analyse spectrale. Le contenu spectral de l'echo est correle a l'etat de la surface irradiee. Certains defauts periodiques peuvent ainsi etre extraits des defauts aleatoires
