Abstract

L'invention concerne l'optique magnétique appliqué, notamment, des dispositifs basés sur l'effet magnéto-optique Faraday. L'objectif de l'invention consiste à soumettre à des essais des articles en matériaux doux conducteurs, magnétiques et non magnétiques, à permettre l'identification d'articles pendant leur marquage et pour la vérification de l'ouverture frauduleuse d'articles. L'invention est basée sur l'enregistrement d'un champ de fuite magnétique de l'article par visualisation de la répartition de la magnétisation dans un film magnéto-optique placé près de la surface de l'article. Avant l'enregistrement dans la zone de contrôle de l'article, un champ magnétique est généré au moyen d'aimants permanents ou par excitation de courants de Foucault. Afin d'identifier l'article, ce dernier est marqué d'un symbole appliqué par changement du relief et/ou de la structure de la surface interne et/ou du volume de l'article. L'invention est appliquable dans l'industrie à des défectoscopes magnéto-optiques destinés à des articles en matériaux conducteurs doux magnétiques et non magnétiques, dans le marquage caché d'articles composés de divers matériaux, pour sceller, de manière dissimulée, des pièces, des coffres, des wagons, des conteneurs, des malles, des valises etc..
