This paper describes a new system to detect defects on the cam shafts of automobiles. The theory, based on laser scattering, is studied first, and then its feasibility is confirmed through basic experiments and simulations. Next, an inspection system is designed and built to verify the effectiveness of the method. The line laser, employed as a light source, illuminates the cam surface and its grey-scale image appears on a CCD as a white line, on which the missing part can be detected when there is a defect. The experimental results show that there is a big correlation between the size of the defect and the missing width. By scanning the laser over the entire surface of the cam shaft, the size and the shape of the defect was measured.
