Abstract

La présente invention concerne un dispositif de balayage électro-optique destiné à l'impression, par photosensibilisation, d'une nappe en défilement continu. Ce dispositif est caractérisé en ce qu'il comporte au moins une source laser 2, un modulateur électro-optique 4 modulant le faisceau laser issu de la source en impulsions de durée variable, un dispositif 6, 7, de déflexion du faisceau laser modulé pour assurer un balayage transversal de la nappe 1, des premier et second codeurs 9, 10 délivrant respectivement des premier et second signaux Y, X, correspondant à la position instantanée du laser respectivement dans les sens transversal et longitudinal de la nappe, et un processeur 13 relié à une mémoire 14 contenant une information à reproduire sur la nappe, aux premier et second codeurs 9, 10, et au modulateur électro-optique 4.
