  • Patent number: 7164955
    Abstract: The process for the on-line characterization of a surface in motion, preferably a galvannealed sheet, essentially comprises an industrial microscope associated with a stroboscopic laser illumination device, a positioning assembly, an assembly for acquiring and processing images. The obtained view fields vary between 125 ?m and 2000 ?m in width, the spatial resolution is at least 0.5 ?m, and the focussing of the system is precise to a micrometer. The images are taken on a product moving at a speed of between 1 m/s and 20 m/s and are frozen by the use of a stroboscopic illumination device with a duration of illumination of at least 10 ns. The obtained images are processed in several steps. A background average level is first of all regularly evaluated in order to be eliminated from each current image. The processed image is then divided into several zones. The sharpness of each zone is evaluated and stored in memory.
