Abstract

Une tête de mesure immergée dans un fluide opaque 2 contient un laser 18 dont les rayons sont projetés à l'aide d'un diviseur 19 sur un miroir de référence 20 appliqué sur un cristal piézo-électrique 21 et sur un miroir de mesure 4 fixé sur la face extérieure un disque de verre 5. Les rayons lumineux réfléchis par les miroirs 4 et 20 interfèrent sur le diviseur 19, dont l'éclairement est mesuré par une photodiode 27. Les ondes provenant d'un générateur d'ultrasons 3 et frappant le miroir 4 sont perturbées par réflexion sur l'objet 1 à contrôler. Le miroir 4 est exploré, point par point, et une image holographique est produite à partir des différences de luminosité enregistrées par la photodiode 27. Application : au contrôle de la face interne de la cuve de réacteurs nucléaires refroidis au sodium.
