Abstract

L'invention se rapporte à la visualisation des déformations de structures déformables par interférométrie holographique. Elle a pour objet un dispositif de visualisation dans lequel l'interférogramme de l'objet, obtenu par double exposition pour un objet en déformation périodique ou par exposition longue devant la période de vibration pour un objet vibrant, est enregistré dans un cristal électro-optique et photoconducteur auquel est appliqué un champ électrique sensiblement orthogonal à la direction moyenne des franges. L'interférogramme est observé dans un plan image ou enregistré dans un tube à mémoire dans le cas où l'on souhaite garder l'information car la lecture est destructive de l'information. L'invention s'applique au contrôle non destructif de pièces mécaniques placées sous contrainte.
