Automated surface inspection is far more than spotting local defects. A reliable detection of voids, blobs, or contaminations in nonwoven material goes without saying when we speak of today’s vision systems. However, yield increase and even faster return-on-investment can be achieved with inspection systems that offer additional process monitoring features. New innovations in LED lighting, CCD camera design, and signal processing permit measuring of optical properties using the same hardware as the defect detection system. This paper will demonstrate how vision cameras can be used to fill the gap between smaller size defect detection and spot-measurement gauging.
