ABSTRACT:
To inspect a ball while it is spinning, a semicircular array of balanced light sources illuminate the ball, each source being directional to illuminate a restricted zone. An array of light detectors adjacent the sources are arranged for each to detect specularly reflected light from the ball originating from a limited number of light sources and a detector channel for each detector analyzes changes in received light to detect ball surface defects. No lenses are required and the sources and detectors are formed to allow compact packaging near the ball surface.
