Abstract

A system for scanning precious stones using laser radiation has been developed. A diagram of the developed laser scanning facility has been drawn up. A review of defects that are most common in gem crystals and which can help in creating a map of crystal defects has been carried out. The description of the technique used in the creation of the product passport is given. The minimum sizes of objects that we can detect using this setting have been set. The probability of reliable detection of a defect in the object under study is calculated. Markers necessary to establish the uniqueness of a gem are identified. Experiments have been carried out using semiconductor lasers with wavelengths of 405 nm and 532 nm. As a result, it was found that the installation is working properly and is capable of mapping the defects of objects transparent in the optical region. To increase the efficiency of the installation, a ready-made database was compiled, which included the most common defects that can be found in gemstones. For a convenient and quick search for defects in the database, a hierarchical system for ordering defects was proposed. After scanning the crystal, the resulting data is recorded into the personal passport of the product, which will allow it to be identified in the future.
