An apparatus for measuring the contour of a surface

摘要

An apparatus for measuring the contour of a surface includes a high intensity light source and optics for projecting a line off light on the surface to illuminate a selected contour feature of the surface. An optical detector generates an image of the selected contour feature illuminated by the line of light, and a processing unit fits at least one contour segment to the image of the selected contour feature and determines contour characteristics from the contour segment. $$
