<p>An optical beam scanner (50). The scanner (50) includes a beam centering device (58) that directs a light beam (52) onto a beam scanning device (60). The beam centering device (58) can compensate for positioning errors in the light beam (52). The scanning (60) and centering device (50) may each have feedback loops used to control the scanning and position of the beam (52), respectively.</p> |
