Abstract of corresponding document:
WO8002393
The device is comprised of an optical multiplexor directing sequentially and periodically a laser beam onto an array of discrete target points, wherein the laser beam is focused on a rotating mirror (12) by means of a converging lens (10). The beam reflected by the mirror (12) scans an array of adjacent converging lenses (14), of which the focal plane is situated also on the reflecting surface of the mirror (12). The beams are passed through a second system of converging lenses (18) located in another path of beams, these converging lenses (18) being each associated to one of the first converging lenses (14) and having their focal plane on the upper surface of the substrate (20) to be treated. If the target points are on a strip of paper, for example cigarette paper, endlessly and in motion, this strip is perforated at high speed with very fine holes.
