Paper Abstract

A coherent optical method to measure the surface characteristics of rolling material e.g. paper on line without mechanical contact in industrial enviroument is presented. This method is based on the optical heterodyne detection of light scattered into a single radiation mode by the rough surface. The detection is followed by an appropriate signal processing that makes characterization of the surface smoothness by parameters called "correlation lengths" indicating the average size of uniform surface elements. These parameters show good correlation with other, widely used static surface roughness measurement methods. Furthermore they gi're the possibility of deeper insight into the surface structure of different types of paper.
