Abstract
An optical surface inspecting system in accordance with the present invention forms still pictures of the surface of a rolling roll while the rolling roll is rotating. The optical surface inspecting system comprises a housing box provided with a window in its front wall, a stroboscopic illuminating device contained in the housing box, a television camera contained in the housing box, and a water droplet removing mechanism combined with the housing box. The water droplet removing mechanism removes droplets of cooling water scattered on the surface of the window, so that the television camera is able to pick up accurate images of the surface of the rolling roll while the rolling roll is rotating.
