Differential gear appearance inspection

For the inspection of the sides of cylindrical targets such as gears for remaining black scales, stains, flaws, or dents, it was difficult to apply lighting evenly. With a line scan camera, images of cylindrical shapes can be captured continuously. Also, LumiTrax™ specular reflection mode allows for the detection of linear flaws, dents, and stains with a single captured image.
