PART INSPECTION APPARATUS

摘要

A plurality of light line generators (72) generate associated beams of light (26) that intersect a part (14) to be inspected. Each beam of light (26) illuminates at least one side of the part (14) with a line of light occluded by the part (14), and at least three light responsive sensors (104) provide for generating a signal (24) responsive to an occlusion of a corresponding line of light on a corresponding side of at least one side of the part (14), wherein each of the light responsive sensors is responsive to an occlusion at a different azimuthal locations. A processor (28) analyzes the signals (24) in relation to a measure of relative location of the part (14) from a motion (18) or position sensor. The part (14) may released from a clamp (52) to drop through the beams of light (26), or the beams of light (26) may be moved relative to the part (14).
