ABSTRACT:
An improved method and apparatus for inspecting the curved surface of a stationary article includes a mirror which is moved to direct a beam of light from a light source through a lens against each point of an arcuate series of points on a curved surface of the article. A second lens focuses beams of light reflected from the article onto a linear detector. The distance between locations at which the reflected light beams are focused on the linear detector corresponds to the distance at which points on the surface of the article are offset due to the curvature of the surface of the article.
