CA 2114109
The disclosure relates to a laser marking system, using a displaceable mirror to cause the path of the laser beam to scan in one direction. The mirror is conveniently controlled by at least one flexure hinge driven by a piezoelectric device, an electro-stric- tive device or a magneto-strictive device. In one disclosed embodiment two mirrors (15, 16) are provided, each mirror (15 or 16) having a flexure hinge device (18, 19) individual thereto; and the displacements applied to the said flexure hinge devices (18, 19), via respective driving devices (20, 21), cause the mirrors (15; l6) to scan the path of the laser beam (13) in a series of steps in one direction of scan: A computer (11), arranged to drive the flexure hinge driving devices (20, 21), also controls the firing of the laser (l2) in accordance with a predetermined programme.
