A device for measuring the deformation of a mechanical test specimen, and including a pressing member (3) for stressing a substantially flat specimen (16) in controlled manner by means of a punch (25); a Michelson interferometer having an optical branch (9d) defined optically by a first face (16b) of the specimen (16), and for generating interference images related to the deformation of the specimen (16); a telecamera (44) for acquiring and digitizing the interference images; and a processor (27) for processing the digitized images and controlling the measuring process fully automatically. The interferometer (9) may alternatively perform white light interferometry measurements, ESPI measurements, or ESPI profilometry measurements, by simply substituting the light source and control software.

Un dispositif permettant de mesurer la déformation d'un échantillon soumis à une épreuve mécanique comprend un élément presse (3) qui applique une contrainte sur un échantillon sensiblement plat (16) d'une manière commandée au moyen d'un poinçon (25); un interféromètre Michelson comprenant une branche optique (9d) définie par une première face (16b) de l'échantillon (16), qui génère des images interférentielles liées à la déformation de l'échantillon (16); une télécaméra (44) qui effectue l'acquisition et la numérisation des images interférentielles; et un processeur (27) qui traite les images numérisées et commande le processus de mesure de manière entièrement automatique. L'interféromètre (9) peut également effectuer des mesures par interférométrie à lumière blanche, des mesures ESPI (interférométrie électronique par granulation cohérente) ou des mesures de profilométrie ESPI; il suffit pour cela de remplacer la source de lumière et le logiciel de commande.
