Abstract

Il est proposé un procédé de contrôle d’une pièce (10), implémenté dans un système optique (1) configuré pour analyser des pièces de phase majoritaire biréfringente. Le procédé comporte : - émettre un faisceau incident (101) vers une surface (100) de la pièce (10), - polariser linéairement le faisceau incident (101) selon un premier axe de polarisation et transmettre un faisceau incident polarisé (102) sur la surface (100), - polariser linéairement le faisceau réfléchi (103), issu de la réflexion du faisceau lumineux incident polarisé (102) par la surface (100), selon un deuxième axe de polarisation perpendiculaire au premier axe et transmettre un faisceau réfléchi polarisé (104), - obtenir une image représentative de réflexions sur la surface, - déterminer si au moins une zone, dite zone claire, de l’image présente une intensité lumineuse supérieure à un seuil prédéfini, - détecter un défaut lorsque la zone claire vérifie un critère géométrique prédéfini. Figure à publier avec l’abrégé : Fig. 1
