Résumé : In the field of composites, Holographic Interferometry (HI) is particularly well adapted for the localization and interpretation of the defects like delaminations, non-adherence and cracks. Strong inhomogeneities (of shape and composition) prevent other non destructive methods to be used except Ultra-sonic method (US) but it is expensive and slow. In this paper, we analyze and compare the different results obtained by Holographic Interferometry and by Ultra-Sonic method in function of external fields applied to the object under test.
