Abstract
A system for sorting articles includes a detector system having a plurality of narrow bandwidth sources of electromagnetic energy sequentially illuminating articles passing through the detector system, the detector system further including a collector for collecting electromagnetic energy reflected from the articles; a deflector for deflecting selected articles toward an alternative destination; and a control system, operably connected to the collector and the deflector, for actuating the deflector in response to a sensed parameter of the electromagnetic energy collected in the collector.
