VERFAHREN ZUR IDENTIFIZIERUNG VON INDIVIDUELLEN OBJEKTEN ODER GEBIETEN.

摘要

In order to separate diamonds from gangue, the particles 2 of the gangue are carried along a belt 1, and are irradiated with a beam from a laser 3. The luminescence emitted by the particles 2 is then detected by two spaced optical modules 5,5 min . The difference in the luminescence detected is related to the nature of the material, and a simple microprocessor 11 and ejection jet 12 can be used to eject diamonds into a sort bin.
