摘要 |
A method and apparatus for measuring surface irregularities on articles such as curved automotive glass are provided wherein two contact points on a sensor head establish a chord at a segment of the surface and a probe measures the distance of the surface from the chord between the contact points, thereby permitting calculation of the local radius of curvature as the surface is scanned.
