SORTING SYSTEM USING NARROW-BAND ELECTROMAGNETIC RADIATION

摘要

A system (10) for sorting articles (1000) includes a detector system (100) having a plurality of narrow bandwidth sources of electromagnetic energy (110) sequentially illuminating articles passing through the detector system, the detector system further including a collector (120) for collecting electromagnetic energy reflected from the articles; a deflector (70) 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.
