Shearography is a full-field speckle interferometric technique used to determine surface
displacement derivatives. For an interferometric technique, shearography is particularly …

This paper presents the activities in the field of shearography in chronological order and
highlights the great potential of this holographic measurement technology. After a brief …

Advanced composites are increasingly used in aerospace, naval, and automotive vehicles
due to their high specific strength and stiffness. However, the mechanical properties of …

Nondestructive evaluation using shearography requires a way to stress the inspection
target. This technique is able to directly measure the displacement gradient distribution on …

Anisotropic stiffness properties of sheet materials can be determined by measuring the
propagation of Lamb waves in different directions, but this typically requires multiple …

A new method for imaging flaws in plate and shell structures is presented. The method
employs two-dimensional ultrasonic surface wave data obtained by optical electronic …

We present a novel capability of the TV holography technique applied to the non-destructive
testing of mechanical parts or structures with the form of a plate or a shell, which consists of …

This article presents an application of a speckle interferometry technique with video
doubling, called" shearography". This technique can be used for near real time imaging of …

Les travaux de recherche présentés dans cette thèse contribuent au développement du
contrôle non destructif (CND) des plaques minces constituées de matériaux composites …

We study the scattering of transient, high-frequency, narrow-band quasi-Rayleigh elastic
waves by through-thickness holes in aluminum plates, in the framework of ultrasonic …
