Paper Abstract

A big challenge for automated industrial inspection systems is the hundred percent in-line surface inspection. Due to material speeds up to 10 meters per second and material widths of several meters the amount of data received by the sensor systems is very large. In most cases the material flow is endless and therefore it is necessary that the complete inspection system works in real realtime. Nearly 25 years ago the first systems based on laser scanning technology were introduced into industry. At the moment approximately more than one thousand laser scanning systems are working world wide. Within the last five years a competitive sensor system, the CCD camera, became commercially available. In our paper we will give an overview and, if necessary, a closer look on the different items of both technologies. In comparison we will discuss advantages and limitations of both systems. This discussion is not based on pure theory but mostly on real experiences. Therefore a couple of industrial applications are shown. In conclusion we will give a short outlook on future developments in sensor technology and evaluation techniques.
