<p>A deflection device (1) for deflecting a laser beam (2) for carrying out thermal surface treatments on splined elements (3) comprises two mirrors (11,12) rotating at the same speed about a respective axis (13,14), and optionally a mirror (15) stationary in an intermediate position. The mirror (11,12) are inclined at a predetermined angle to their respective shafts (13,14). The inclination of the rotary mirrors (11,12) may be adjustable relative to the respective axis, as well as the relative phase of each mirror, so that the laser beam at the outlet of the device (1), describes a squashed annular trajectory (24) substantially comparable to a straight line segment. <IMAGE></p> |
