摘要： The invention provides a method and apparatus for positioning a surface (30) in a desired orientation. There is provided a movable member (10) supported for movement by a fixed member (40) and the movable member has an optical element, e.g. a flat mirror (30) fixedly attached thereto. In one embodiment the mirror scans a radiation beam incident thereon along a single axis. In a second embodiment, the radiation beam is scanned in two mutually perpendicular axes. A magnetic element (50) having a north and a south magnetic pole is fixedly attached to the movable member (10). A magnetically permeable stator element (70), that is stationary with respect to the movable member (10) and the magnetic element (50), is placed in the field of the magnetic element (50) such that the stator element (70) and said magnetic element (50) mutually generate a magnetic traction force between them. A current coil (60) is wound around a portion of the stator element (70) and a current driver (400) is provided for driving a current in the current coil (60). The current induces an electromagnetic field in the stator element (70) and an electromagnetic force acts on the magnetic element (50) for controlling movement of the surface (30) with respect to the fixed element (40). A radiation beam source (502) may be directed onto the movable mirror surface (30) and scanned by the movement of the mirror to direct the radiation beam in a desired propagation direction.

摘要： A laser processing system is disclosed for providing a relatively small velocity of a laser beam at target location while at least one scanner scans at a relatively larger velocity. The system includes a laser source, a first scanning unit, a beam expander, a second scanning unit and focusing optics. The laser source is for providing a pulsed laser output having at least one beam with a beam dimension. The first scanning unit is for scanning the laser output in a first direction along a first axis at the target location. The beam expander is for receiving the laser output and for modifying a beam diameter of the laser output and providing a modified laser output. The second scanning unit is for scanning the modified laser output from the beam expander in a second direction along the first axis at the target location. The second direction is substantially opposite to the first direction along the first axis such that a net velocity of the modified laser output along the first axis at the target location may be made to be effectively zero during a laser pulse. The focusing optics is for focusing the modified laser output toward the target location.
