Abstract
On-line inspection of fast moving surfaces is one of the domains of laser scanning methods, especially whenever extremely small flaws are to be monitored on high quality products. Results of surface inspection on rolled aluminum based on several years' experience with several generations of inspection equipment are presented. Surface texture and characteristics of aluminum flaws require a problem related design of the laser scanner hardware for operation in the environment of a rolling mill plant. Fast intelligent data processing develops the inspection equipment to the center part of a plant-wide quality concept that strongly supports the idea of producing quality instead of only selecting quality.
