More Information
Summary:A contour measuring system is disclosed in which the contour, surface texture and roundness of cylindrical members can be readily determined optically. Specifically, a slit camera converts the cylindrical surface to a planar surface, a picture. The illumination for the picture is provided by thin sheets of light in a plane approximately parallel to the axis of the cylinder and tangential to the surface. The image thus recorded resembles a topographical map of the cylindrical surface.
