Abstract

La présente invention concerne un appareil pour inspecter le contour de la section transversale d'un article. L'appareil est basé sur le principe de projeter un modèle lumineux sur l'article à l'endroit du contour de la section transversale à inspecter et l'image de ce modèle lumineux est projetée sur un écran. La présente invention est applicable pour examiner le contour de la surface d'une aube réalisée en une seule pièce avec sa plate-forme.
