Detector for glass-ceramic fragments within broken glass mixtures with polarization filters positioned between the stream of broken glass mixture and respectively a light source and a receiver

摘要

The glass-ceramic fragment detector for broken glass mixtures uses polarization filters (10, 12) with their polarization filters oriented at a nonzero angle relative to one another are positioned between the stream (4) of broken glass mixture and respectively a light source (9) and a light receiver (11).
