Title
(EN) APPLYING MARKS TO A SURFACE OF A MEDIUM
(FR) APPLICATION DE MARQUES SUR UNE SURFACE D'UN SUPPORT
Abstract
(EN)
An optical sensor device (10) includes an application module (12) for applying an irregular pattern of marks to a surface of a medium and an optical detector module (14). The optical detector module (14) acquires images of the applied marks and may determine an advancement speed of the medium based on the acquired images.
(FR)
L’invention concerne un dispositif de capteur optique (10) qui comprend un module d'application (12) permettant d'appliquer un motif irrégulier de marques à une surface d'un support et un module de détecteur optique (14). Le module de détecteur optique (14) acquiert des images des marques appliquées et peut déterminer une vitesse d'avancement du support sur la base des images acquises.
