Abstract: A method and system for inspecting a manufactured part at an inspection station are provided. A supported part is rotated about a measurement axis so that the part moves at predetermined angular increments during at least one rotational scan. A backside beam of collimated radiation is directed at and is occluded by the supported part at each of a first plurality of consecutive increments of movement to create a stream of unobstructed portions of the backside beam in rapid succession passing by and not blocked by the supported part. A frontside beam of radiation is directed at and is reflected by the supported part at each of a second plurality of consecutive increments of movement to create a stream of reflected portions of the frontside beam in rapid succession. The streams of reflected and unobstructed portions are detected at the inspection station to obtain electrical signals which are processed.

Abstract: A high-speed, high-resolution, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspected parts are provided. The method includes consecutively transferring the parts so that the parts move along a path which extends from a supply of parts and through an imaging station. A triangulation-based sensor head is supported at the imaging station. The sensor head is configured to generate focused lines of radiation and to sense corresponding reflected lines of radiation. The focused lines are delivered onto an end surface of each part to obtain a corresponding array of reflected lines of radiation. The sensor head senses the array of reflected lines to obtain a corresponding set of 2-D profile signals. The set of profile signals represent a 3-D view of the end surface. The set of 2-D profile signals of each part is processed to identify parts having an unacceptable defect.

Abstract: A method and system for optically inspecting the entire outer peripheral surface of a part are provided. The system includes an enclosure which allows movement of a part relative to the enclosure both prior to and after inspection within the enclosure. An illumination assembly simultaneously illuminates a plurality of exterior side surfaces of the part which are annularly spaced about the axis of the part with radiation when the part is at a predetermined location within the enclosure to obtain corresponding reflected radiation signals. A plurality of lens and detector assemblies are provided. Each of the assemblies forms an optical image of one of the illuminated exterior side surfaces from the reflected radiation signals and detects the formed optical image within the enclosure. A processor processes the detected optical images to obtain a continuous, seamless, 360° panoramic composite image of the peripheral surface of the part.
