Detector for surface defect
专利汇可以提供Detector for surface defect专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the detecting cost and the energy loss by irradiating the light obtained directly from an electric energy onto the surface of a body to be detected via a light conducting body and projecting lens system and by analyzing and processing the signal obtd. from the reflected light through photodetecting system and signal transmitting means.
CONSTITUTION: A light source part 12 which converts directly the electric energy transmitted from an electric power source 12A via a metal cable 14 is arranged with the isolation from a body 10 to be detected and the light is irradiated onto the body 10 to be detected via input optics system 16, optical fiber 18 and projecting lens system 22. The electric signal changed from the reflected light with a photodetecting camera 24 is analyzed and processed by a signal processing part 28 via a signal cable 26 to discriminate automatically the detect, etc. on the surface of the body to be detected 10. A part of the electric signal is fed back to the power source 12A via the signal cable 30 to make the background level of the reflected light constant always.
