Abstract: A laser machining system for machining a work-piece includes a laser scanning head, external optical subsystems, and an image acquisition device. The external optical subsystems correspond to optical channels that include a first optical channel and a second optical channel. The laser scanning head controls an optical path so that a laser beam is directed and focused on the work-piece through the first optical channel and the second optical channel at different times. The first optical channel and the second optical channel correspond to respective specific portions of the work-piece to be machined by the laser beam. The image acquisition device is positioned to view the work-piece through the optical path. The image acquisition device acquires via the first optical channel one or more images of the work-piece to determine a displacement of the work-piece with reference to a best optical focus position of the second optical channel.

Abstract: Embodiments of the present disclosure are directed to systems (300), devices and methods for machining a work-piece from a plurality of directions using a single laser beam and galvanometer scan head (302). In some embodiments, such a system includes, for example, a scanning galvanometer head (“scan-head”) (302), having one or more mirrors (323) for directing a laser beam in at least one plane. Preferably, in some embodiments, the scan-head includes two mirrors for deflecting the laser beam in the at least one plane (e.g., an X-Y plane). A plurality of second mirrors (312A, 312B, 312C) is arranged after the scan-head (302) to direct the laser onto a predetermined portion of the exterior of the object to be machined. In some preferred embodiments, there are three such second mirrors (312A, 312B, 312C) each to direct the laser over a 120 degree area of the object.
