ABSTRACT:
An impurity detector using scattered electromagnetic radiation from a sample of bulk material. It includes a generator of a narrow beam of modulated and linearly polarized electromagnetic radiation directed toward the sample. One or more radiation detectors, the number depending on generator stability and sample characteristics, are responsive to scattered modulated radiation polarized parallel to the polarization of the radiation from the generator. The one or more detectors generate a signal indicating the intensity of such scattered, modulated, and polarized radiation representing a normal sample's angular scattering spectrum. A change in the output of the detector indicates the presence of an impurity in the sample.
