Method and apparatus for scanning |
摘要 |
The surface of a part to be identified or inspected is scanned by a laser beam projected normal to the surface to be scanned from the end of a rotating arm in a circular scan pattern. A small collector lens is fixed to the end of the rotating arm and has a hole through which the projected beam passes. The part moves across the scan pattern in a direction perpendicular to the projected beam, and intensity of reflected light received by the lens and transmitted to a detector provides precision information concerning surface characteristics, orientation and discontinuities.
