ABSTRACT:
The invention is directed to a method and apparatus for detecting foreign matter including small particles of organic materials such as plastics within a layer of tobacco. The tobacco is irradiated with a plurality of selected NIR radiation wavelength bands. Data representative of the NIR radiation exiting the tobacco is compared to a predetermined reference representative of a plurality of different tobacco samples to determine whether the inspected tobacco contains foreign matter.
