ABSTRACT:
A sorter is described that optically differentiates acceptable objects from unacceptable objects. The sorter illuminates the objects as they move in a stream through a viewing zone with both visible and infrared light. The detecting system and circuit provides electric signals proportional to the light transmitted or reflected by the objects to a microcomputer system which in turn activates a rejection mechanism if unacceptable objects are viewed. The microcomputer system determines what objects are unacceptable by comparing signals for objects being viewed with stored signals for acceptable objects.
