METHOD AND DEVICE FOR IDENTIFYING JEWELLERY AND GEMS

摘要

A method and device for identifying jewellery and gems. The method comprises the following steps: (a) placing a sample under detection at a light-out hole on a bearing surface of an objective table, transmitting excitation light onto the sample under detection via the light-out hole using an optical probe located below the bearing surface and collecting Raman light coming from the sample under detection; (b) obtaining a Raman spectrum curve of the sample under detection by means of the collected Raman light of the sample under detection; and (c) comparing the Raman spectrum curve with a standard Raman spectrum chart library of jewellery and gems so as to identify the sample under detection. The method and device can realize highly-efficient, simple and convenient, and accurate identification on jewellery and gems samples.
