Abstract
Procédé de production d'un signal au passage d'une discontinuité entre deux champs présentant un contraste par un lieu prédéterminé par rapport à un récepteur comprenant deux cellules photoélectriques dont les sorties sont combinées pour la formation de ce signal de commutation. Le procédé consiste à former la différence des signaux de deux récepteurs photoélectriques 11 et 12 se succédant dans la direction du déplacement et à déterminer leur maximum, à comparer une fraction de ce maximum à la valeur momentanée de la différence et à déclencher le signal de commutation à l'instant auquel cette valeur momentanée est égale à la fraction précitée. Application à la détection et avec précision d'un repère en impression multicolore.
