Title (EN) FLEXIBLE DISK MODE OBSERVER
(FR) DISPOSITIF POUR LA SURVEILLANCE DU MODE DE FONCTIONNEMENT DES DISQUES SOUPLES
Abstract:
(EN) System (100) and method for determining displacement or alteration of flexible media (220) under different operating conditions. The system includes a reference pattern (130) which is projected onto the surface of the flexible media (220). The modes of displacement can then be visualized by viewing the reference pattern reflected from the surface of the flexible media.
(FR) L'invention concerne un système (100) et un procédé pour la surveillance du déplacement ou de l'altération des disques souples (220) dans différentes conditions d'exploitation. Le système projette un motif de référence (130) sur la surface des disques souples (220), ce qui permet de visualiser les marges de déplacement en se fondant sur la réflection du motif de référence à la surface des disques souples.
