Laser beam positioning system

To provide a method and apparatus for targeting the radiation beam. Beam-steering mirrors and beam capture mirror is movably disposed along the path of the light. Controller moves the beam steering mirrors and beam capture mirror in the xy plane, by rotating the mirror, while targeting beam onto a target position on the surface, a substantially constant optical path length for all target positions on the surface keep to. Rotating the surface by rotating the actuator, to a location accessible to all target positions by the beam targeting optics. The inaccuracy of targeting and optical path length, providing an variable focus lens having an operating opening and / or optical range detector beam incident point, the whole can be corrected by communicating with the controller.
