Abstract

L'INVENTION CONCERNE UN APPAREIL ET UN PROCEDE DE CORRECTION DES IMPERFECTIONS D'UN MIROIR POLYGONAL UTILISE POUR UN BALAYAGE PAR FAISCEAU LASER. UN DETECTEUR EN DEUX MOITIES EST PLACE EN TETE DU BALAYAGE PRODUIT PAR LE MIROIR POLYGONAL. QUAND LE FAISCEAU SE TROUVE DANS LA PREMIERE MOITIE DU DETECTEUR, UN SIGNAL EST PRODUIT ET APPLIQUE A UN MODULATEUR POUR DEVIER LE FAISCEAU VERS LA SECONDE MOITIE. QUAND LE FAISCEAU SE TROUVE DANS LA SECONDE MOITIE DU DETECTEUR, UN AUTRE SIGNAL EST PRODUIT POUR DEVIER LE FAISCEAU VERS LA PREMIERE MOITIE. L'INVENTION S'APPLIQUE NOTAMMENT A L'ENREGISTREMENT DE DONNEES SUR UN SUPPORT PHOTOSENSIBLE.
