Abstract

Procédé de guidage de l'énergie d'un pinceau laser. L'écran fluide 2 supporte une image 7 resultant de la projection par le projecteur 1. Un laser 4 émet un pinceau 5 qui s'appuie sur le contour de l'image 7 et traverse l'ecran pour percuter un objet 6. Cet objet 6 peut être indifféremment une surface à impressionner, à usiner, à guider ou à coder ou décoder.
