Laser-aided separation of diamonds

A new technology for separation of diamonds is proposed: a combined use of the Rayleigh and Ramanlight Scattering in a two-stage separator. A brief description of various units for detection is given. Results of work on development and experimental checking of such a separator are presented. The method of laser-aided separation of diamonds based on the principle of elastic (without any frequency shift) light scattering has no analogs and is protected by a patent.
