DEVICE AND METHOD FOR GUIDING A LASER BEAM WITH A VIEW TO ROTATIONAL AND LINEAR DISPLACEMENT, IN ORDER TO VARY THE ECCENTRICITY OF THE LASER BEAM

The invention relates to a device and a method for guiding an impact trajectory of a laser beam (C) exiting from a housing (2), in which a lens (10) is used to collimate a laser beam (A) arriving from a laser source and entering the housing, the lens (10) is made to rotate about an axis (ω, x) eccen...

Zusammenfassung:	The invention relates to a device and a method for guiding an impact trajectory of a laser beam (C) exiting from a housing (2), in which a lens (10) is used to collimate a laser beam (A) arriving from a laser source and entering the housing, the lens (10) is made to rotate about an axis (ω, x) eccentric relative to the optical centre (0) of the lens, and a progressive, controlled variation in the offset (5) of the lens (10) is achieved, sometimes during rotation of the lens (10) and sometimes for a given angular position of the lens (10). Dans le dispositif et dans le procédé de guidage d'une trajectoire d'impact d'un faisceau laser (C) sortant d'un boîtier (2), on collimate par une lentille (10) un faisceau laser (A) arrivant d'une source laser et entrant dans le boîtier, en imprimant à la lentille (10) une rotation autour d'un axe (co,x) excentré par rapport au centre optique (0) de la lentille, et on pilote une variation progressive contrôlée d'excentration (5) de la lentille (10), par moments pendant la rotation de la lentille (10), et par moments pour une position angulaire donnée de la lentille (10).
