Abstract

Cette invention peut être utilisée à l'échelle industrielle afin de diagnostiquer les défauts de pièces et d'articles métalliques particulièrement critiques, dans la production de matériaux conducteurs magnétiques et durs, magnétiques et mous ou non magnétiques et d'articles faits de ces derniers, dans le contrôle de l'enregistrement sur différents supports magnétiques, en phonoscopie criminelle, afin de contrôler l'authenticité de billets de banque ou autres papiers valeurs en fonction de critères magnétiques, afin de restaurer des informations partiellement détériorées ou perdues sur quelque support magnétique que ce soit, y compris des signalogrammes magnétiques à partir d'une «boîte noire», afin de mesurer sans contact un courant électrique dans des lignes à haute tension de transmission électrique et de répartitions ultra-faibles de densité de courant dans des microcircuits, afin de mesurer les courants électriques de vaisseaux sanguins minuscules à l'aide de tomographes et, enfin, afin de mesurer des champs magnétiques dans l'espace ainsi que dans des conditions de radiations élevées et de basses températures. Cette invention permet d'accroître la sensibilité ainsi que la résolution tridimensionnelle lors de la visualisation d'un champ magnétique non uniforme. Ce convertisseur magnéto-optique (11) comprend un substrat transparent (1) sur lequel est appliqué un film monocristallin de ferrite de type grenat (2). Ce film (2) possède une anisotropie magnétique telle que les vecteurs de magnétisation sur ce dernier, en l'absence de champ magnétique, sont déviés de son plan selon un angle allant jusqu'à 25°. Le champ de saturation du film (2), le long de la normale à ce dernier, varie de 10 à 20000 Oe.
