Abstract

La présente invention concerne un procédé et un dispositif de mesure dynamique du diamètre d'un fil sous forme numérique. Une source lumineuse 1 projette l'ombre d'un fil 2 sur un écran 3. Aux limites de l'ombre portée sont disposés des registres photosensibles linéaires du type à transfert de charge 4 et 5. Par suite de l'application de signaux d'horloge, le nombre de cellules non éclairées de chacun des registres 4 et 5 est compté par des compteurs. Ces nombres n1 et n2 sont additionnés en tenant compte de coefficients d'échelle appropriés avec la valeur b correspondant à la distance entre les registres pour fournir une mesure instantanée du diamètre du fil 2 indépendamment de ses vibrations. Application à la mesure du diamètre de fils en cours de fabrication.
