Claim Text:
1. A laser machining system for machining a work-piece, the system comprising: a laser scanning head; external optical subsystems corresponding to optical channels comprising a first optical channel and a second optical channel, the laser scanning head controlling 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 corresponding to respective specific portions of the work-piece to be machined by the laser beam; and an image acquisition device positioned to view the work-piece through the optical path, the image acquisition device acquiring 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.
