Abstract

Dispositif optique pour mesurer à distance sans contact le diamètre extérieur d'objets de section circulaire dans lequel l'objet est éclairé par un faisceau de lumière parallèle, et dans lequel l'image de l'ombre de l'objet est recueillie sur un récepteur à photodiodes. Il comprend entre l'objet éclairé et le récepteur au moins un système optique afocaL Application notamment aux mesures de diamètres de tubes.
