This paper reports a new method for detecting defects on the paint panel surface of a car body, which is light scattering method based on optical Fourier transform theory. In this paper, an incident laser beam emitted from He-Ne laser is illuminated onto the test surface. Light reflected from the test surface is directed to a CCD camera through the Fourier transform lens. Then, the scattered light intensity distribution is characterized by the defect size of the test paint surface. The defect size ranges of 5∿50μm in height and 500∿2000μm in width are measurable by computing the intensity ratio of diffuse reflection to specular reflection of panel surfaces. The experiment results show that the proposed method using the laser light is available for detecting defects on the paint panel surface of a car body.
