A method and apparatus for examining the surface condition of a traveling metal strip in the process of being continuously cast for detection of scarfs, if any, produced on said surface, wherein a light emitter projects light beams of short waves or those containing said short waves and other waves on a traveling metal strip in the process of being continuously cast; among the reflections of the projected light beams, only those consisting of short waves are received by the light detector through a filter; a flat hood surrounding a light path extending between the light emitter and light detector is set in a cooling chamber; compressed air streams run through the flat hood to air purge or clean the environment of the light path; a signal issued from the light detector is processed by an image memory; the shade image of the traveling metal strip is continuously displayed on the screen of a monitor television set; and the surface condition of the traveling metal strip is examined on the screen to detect scarfs, if any, produced on said surface.
