ABSTRACT:
An optical method of detecting impurities in powders. The detector employs a laser (10) as a source of radiation which impinges upon a stream of powder and impurities as they are blown through a clear glass tube (14). The scattered radiation then stimulates photoresistors (18) so as to produce a signal which can be displayed and recorded on a chart recorder or computer display device (26).
