Abstract

Appareil de balayage optique à faisceau laser. Il comporte un élément présentant une surface réfléchissante plane, un mécanisme destiné à déplacer cet élément, un faisceau laser qui frappe ladite surface et qui est réfléchi par celle-ci, un élément qui renvoie le faisceau laser réfléchi vers ladite surface plane afin que celle-ci le réfléchisse une seconde fois et inverse ainsi sur 180 degrés une composante angulaire dudit faisceau laser, cette composante étant ainsi supprimée du faisceau. Domaine d'application : production d'une Mage d'un objet sur un support photosensible.Laser beam optical scanning device. It comprises an element having a flat reflecting surface, a mechanism intended to move this element, a laser beam which strikes said surface and which is reflected by the latter, an element which returns the reflected laser beam towards said flat surface so that it- ci reflects it a second time and thus reverses an angular component of said laser beam over 180 degrees, this component thus being removed from the beam. Field of application: production of a Mage of an object on a photosensitive support.
