Title (EN) LASER-BASED METHOD OF FORMING AN IMAGE IN TRANSPARENT OBJECTS
(FR) PROCEDE DE FORMATION PAR LASER D'UNE IMAGE DANS DES OBJETS TRANSPARENTS
Abstract:
(EN) The invention can be used for creating decorative patterns in solid transparent materials. In a first step, a laser beam is formed with different divergences in two mutually perpendicular planes; during the image-forming process which involves displacing the object, the angle between the plane of greater divergence of the laser beam and the surface of the image section to be formed is altered in accordance with the desired contrast in the given image section.
(FR) Cette invention se rapporte à un traitement décoratif de matériaux solides transparents, et consiste essentiellement à générer, au cours d'une première étape, un faisceau laser possédant des divergences différentes sur deux plans perpendiculaires l'un à l'autre. Lors du processus de formation de l'image, durant lequel on déplace l'objet, on modifie l'angle entre le plan possédant la plus grande divergence de faisceau laser, et la surface de la partie d'image devant être formée, ceci en fonction du contraste souhaité de ladite partie d'image.
