Abstract
L'INVENTION CONCERNE UN APPAREIL D'INSPECTION OPTIQUE DESTINE A CONTROLER UN OBJET TUBULAIRE EN MOUVEMENT CONTINU. IL COMPORTE UNE TETE ANNULAIRE A LAQUELLE ABOUTISSENT DES GROUPES DE CONDUCTEURS A FIBRES OPTIQUES AMENANT LA LUMIERE D'UNE SOURCE ET TRANSMETTANT LA LUMIERE REFLECHIE VERS DES PHOTODETECTEURS. CHAQUE GROUPE EST ASSOCIE AVEC UN CANAL COMPRENANT UN AMPLIFICATEUR DONT LE GAIN EST REGLE AUTOMATIQUEMENT EN FONCTION DU SIGNAL DE BRUIT DANS CE CANAL. LE SIGNAL DE PLUS HAUT NIVEAU DANS L'UN DES CANAUX A UN INSTANT DONNE EST COMPARE AVEC UN NIVEAU DE REFERENCE DANS UN COMPARATEUR QUI EMET EVENTUELLEMENT UN SIGNAL DE DEFAUT. L'INVENTION S'APPLIQUE NOTAMMENT A UN APPAREIL DE CONTROLE D'UNE MACHINE DE FABRICATION CONTINUE DE CIGARETTES.
