Ruby fluorescence detection system and method

Abstract

The invention discloses a ruby fluorescence detection system and method. The ruby fluorescence detection system comprises an excitation light source, a first optical filter, a sample table, a three-dimensional electric operating system, a second optical filter, an optical filter conversion device, a lens, an image sensor and a display screen, wherein the three-dimensional electric operating systemis installed at the bottom of the sample table; the first optical filter is installed at the output end of the excitation light source; the image sensor is installed at the top of the lens; the second optical filter is installed at the lens input end of the lens; the optical filter conversion device is installed outside the second optical filter; and the bottom of the lens surface of the lens isopposite to a sample on the sample table. The ruby fluorescence detection system and method can rapidly distinguish and identify various cut natural rubies and synthetic rubies with the diameter of 0.5 mm-30 mm in large quantities.

Description

technical field [0001] The invention relates to the field of gemstone detection, in particular to a ruby ​​fluorescence detection system and a ruby ​​fluorescence detection method thereof. Background technique [0002] In recent years, fluorescence technology has begun to be widely developed in various material detection fields. Since many gem minerals have fluorescent properties, the fluorescent characteristics of such gemstones are excited by ultraviolet light sources, and gemstones can be identified by observing the fluorescent color and structure of gemstones. [0003] At present, the gemstone fluorescence observers used by domestic and foreign gemstone inspection institutions are mainly diamond fluorescence observers, such as DiamondView, SYNHdetect, GV5000, etc. The above-mentioned instruments and equipment are mainly aimed at the fluorescence properties of diamonds, and the ultraviolet light source suitable for exciting diamond fluorescence is selected, and captured b...

AI Technical Summary

Problems solved by technology

[0004] The above diamond fluorescence observer has the following problems when carrying out fluorescence detection of ruby: (1) because the above-mentioned instrument equipment has selected the light source based on exciting diamond fluorescence properties, and this type of light source cannot excite the ruby ​​light source preferably; (2) ) Due to the lack of filters, the above instruments and equipment cannot effectively observe the fluorescent structure characteristics of rubies, because the general fluorescent color of rubies is red tones in different degrees, especially synthetic rubies have strong red fluorescence properties, so it is necessary to use filters to absorb red, so as to be able to Better observe the structural characteristics of rubies; (3) It takes up a lot of space and is not easy to carry; (4) At present, there is no instrument and equipment for the detection and identification of natural rubies and synthetic rubies through fluorescence properties at home and abroad
