摘要

The invention relates to a method and a device for detecting and differentiating between the basic materials, the colors, and the contaminations in granular or tabular substances. The invention is characterized in that the substances are illuminated with a laser beam in a linear manner, and in that the optical radiation re-emitted by the substances is spectroscopically analyzed, and the substances are classified and separated into different groups.
