Abstract

An optical inspection system has been developed to detect the surface quality of flat surfaces. The system monitors surface quality by using a laser scanner sensor which detects spatial differences in the intensity level of the light scattered in various directions. An image processing algorithm has been developed to classify the surface quality either by measuring the average of the intensity difference or by counting the number of defects when a more detailed analysis is necessary.
