Abstract
A method and system for optically inspecting parts are provided wherein the system includes a part transfer subsystem including a transfer mechanism adapted to receive and support a part at a loading station and to transfer the supported part by a split belt conveyor so that the part travels along a first path which extends from the loading station to an inspection station at which the part has a predetermined position and orientation for inspection. An illumination assembly simultaneously illuminates a plurality of exterior side surfaces of the part with a plurality of separate beams of radiation. A telecentric lens and detector assembly forms an optical image of at least a portion of each of the illuminated side surfaces of the part and detects the optical images. A processor processes the detected optical images to obtain a plurality of views of the part which are angularly spaced about the part.
