Abstract
An Automatic Web Inspection System is described which is intended for the detection and classification of defects in the periodic cell structure of ceramic catalytic converter substrates. The system scans the cut ends of ceramic logs and optically processes the reflected light with spatial filtering in the image plane. The outputs of the optical detectors are then processed with electronic logic to classify and count the defects.
