Abstract: PURPOSE:To enable detection of a shallow defect on a rough surface by forming a coat of an appropriate solution on the surface of a substance to be inspected of which the state of the surface is rough, by illuminating the surface of the coat vertically by coaxial vertical illumination and by detecting the luminance distribution of a reflected light therefrom. CONSTITUTION:A substance 1 to be inspected is fixed on an inspection table 3. An illuminating device 4 formed by a tungsten halogen lamp makes coaxial vertical illumination by means of a half mirror 5. A reflected light on the surface of the substance to be inspected is focused on an image-sensing surface of an image-sensing device (two-dimensional photoelectric conversion element) 6. An image processing device 8 subjects a video signal inputted from the image-sensing device 6 to binary- coding and executes a processing of determining a defective part. Besides, a coat 2 of a volatile organic solvent, for instance, is formed on the inspection surface of the substance 1 to be inspected. A part of an illumination light is reflected on the surface of the coat, so that the same effect as making a surface roughness small be obtained, and thereby a difference in luminance between a normal part and the defective part is increased. By emphasizing the contrast of the defective part by said operation when the image is taken in, the detection of a defect in an image processing is facilitated.
