    Method of Non-Contact Scanning of Profiles of Rotating Objects and Evaluation of Their External Dimensions

  • Original language description

    The invention is a method of non-contact scanning of profiles of rotating objects and evaluation of external dimensions, where a rotating object is mounted turnably around a rotation axis, provided with a positionable optical head, an initial scanning point is chosen on the rotation axis, and its position is determined, a measuring plane of an optical micrometer is determined at an angle of 90o +- 45o relative to the surface of the rotating object, points of the surface of the rotating object are scanned in the measuring plane by a collimated beam of the optical micrometer so that a receiver is partially shaded by the rotating object, thereby projecting the points into an edge of the shadow transition and the incident collimated beam of rays on the receiver. The distance R of the points of the surface of the rotating object from the rotation axis and the position on the surface of the rotating object relative to the initial scanning point on the rotation axis are evaluated, the optical head is moved, and the position relative to the initial scanning point is determined. The steps are repeated and the shape of the profile of the rotating object is evaluated.
