Abstract
A laser beam focussed on a moving surface, e.g. of a rolling mill, is modulated by means of a rotating disk with through-orifices. The radial lateral faces of the orifices have, relative to the axis of the laser beam, angles of inclination which are different from each other; this difference in inclination is such that the laser beam deviated by one of the radial lateral faces is then reflected by the opposite radial lateral face towards the zone of the surface which is struck by the laser beam passing, without being deviated, through the orifice. The difference in inclination may be between 15.degree. and 30.degree.. The lateral faces of the through-orifices may be lined with a reflective material.
