METHOD, SYSTEM, AND APPARATUS FOR OPTICAL MEASUREMENT

Abstract:

A method, system and apparatus are provided in accordance with example embodiments for optically measuring workpiece features, and more particularly, to optically measure internal surfaces of round bores and countersinks. Methods include: advancing a probe through a bore and a countersink; and measuring dimensions of the bore and the countersink using a bore laser cone and a countersink laser cone, where the bore laser cone is received at the bore camera lens in response to reflecting from a first reflective surface of the probe to a surface of the bore to a third reflective surface of the probe and to the bore camera lens, and where the countersink laser cone is received at the countersink camera lens in response to the countersink laser cone reflecting from a second reflective surface of the probe to a surface of the countersink to a countersink beam reflector and to the countersink camera lens.
