Abstract
L'invention concerne un codeur angulaire. Ce codeur comprend un disque tournant 10 présentant une série de marques radiales gravées, un détecteur fixe (TFO, TF) un détecteur mobile (TMO ou TM). On effectue une mesure approchée d'angle de décalage entre détecteur fixe et détecteur mobile par comptage de marques défilant devant les têtes. On effectue aussi une mesure fine de déphasage entre le passage d'une marque devant un détecteur fixe et le passage d'une autre marque devant un détecteur mobile. Une mesure de déphasage fin est effectuée. Pour éliminer des erreurs dues aux fluctuations de mesures, on change lorsque c'est nécessaire l'origine des temps pour la mesure fine de déphasage faite à chaque passage de graduation. Applications : codeurs angulaires pour théodolites et autres.
