ABSTRACT:
An optical inspection system for articles moved by a conveyor, in which photo-electric transducers of one or more cameras are directed onto a transverse viewing area to detect light variations in individual articles. A threshold system permits correction for light signals in relation to the angular distance between the article being observed and the camera optical axis. A two-step inspection involves first detecting anomalous light levels, and subsequently detecting the size of each defect.
