Abstract

Le procédé selon l'invention de contrôle de l'état d'une surface courbe (2) de révolution consiste à : - projeter au moins un faisceau lumineux (3) sur la surface (2) par l'intermédiaire d'au moins une tête de projection (5) déportée reliée à une source lumineuse (4) par au moins un élément (6) de conduction de la lumière ; - faire tourner la surface (2) autour de son axe de révolution ; - capturer des images successives des profils lumineux (8) reflétés sur la surface (2) par l'intermédiaire d'au moins un système (7) de capture d'images ; - extraire les profils lumineux - détecter sur les profils lumineux extraits, des minima locaux et des maxima locaux synonymes de défauts de surface.
