Abstract:
The relative position of a plurality of holes through a surface of a member, the holes having been generated by high energy means, such as a laser, which vaporizes material of the member to produce a light flash, is inspected and controlled as the holes are being generated using a light sensing means which is responsive to the light flash and which observes the relative positions of the holes being produced. The light sensing means signals a hole pattern comparison means which compares the actual hole pattern with a preselected hole pattern. Adjustment can then be made to reposition the high energy beam if required to correct undesirable error in the actual hole pattern during generation of the holes.
