Abstract

Système optique de contrôle de fabrication par observation oculaire de la surface d'un produit fabriqué et comparaison avec une image-témoin de référence. Le système comprend un objectif 6 pour viser la surface 3 à contrôler par l'intermédiaire d'un miroir 4. Après déflexion par le miroir 7, une image réelle se forme dans le plan 9 pour etre observée par l'oculaire 8. On place dans le plan 9 des diapositives 14 qui se juxtaposent à l'image Le faisceau éclairant les diapositives est brouillé par traversée d'une lame 16 dépolie à effet directif. Application à tout contrôle visuel de fabrication par comparaison à une image de référence.
