Abstract

ELECTRO-OPTICAL MONITORING SYSTEM A system for viewing a zone to detect the presence of an article carried therein on a conveyor. In one embodiment, the system includes a laser source which projects a line-beam of coherent light toward the zone, which beam is intersected, along a length thereof, by the planar field of view of a reflection detector whose view-plane contains the beam. In another embodiment, the system uses a laser source which projects a planar beam of coherent light which is intersected by the field of view of a reflection detector whose view-field has both length and breadth dimensions where it intersects the laser beam. In both embodiments, the region of intersection of the laser beam and the detector's field of view is spaced from the conveyor. 1.
