Technical Field

The invention relates to the technical field of precious stones, in particular to a precious stone characteristic data acquisition and analysis device based on a mobile phone.

Background

The industrial digitization and the digital industrialization are rapidly developing, and the jewellery professional teaching and jewelry inspection business is no exception. However, at present, instruments and equipment for jewelry professional teaching and conventional jewelry detection, such as a handheld spectroscope, a dichroic mirror, a color filter and the like, do not have the function of collecting data, which becomes an absolute obstacle for digitized upgrading of the precious stone teaching and conventional detection business, and upgrading and reforming the instruments and equipment so as to adapt to the current industrial digitized upgrading and reforming are imperative.

The device can test important parameters of precious stone materials, is very important for cognizing precious stones and conventional detection and identification of precious stones, and the basic principle of design of the device still occupies an important position in the current precious stone materials field. These devices are portable, simple, and practical to locate, and therefore are widely accepted and used in the jewelry industry; however, because of the positioning, the instruments and equipment are designed independently, the instrument observation window is narrow, the working distance is short, the management is messy and inconvenient in use, and the experience is poor. The method is necessary to integrate and reorganize functional modules of various conventional instruments and equipment, optimize an observation mode method and improve experience.

Some of the conventional gem instruments and equipment are designed and developed, and almost no quality change occurs after hundreds of years. Parameters that can be used for gemstone authentication, quality assessment, such as the polarization of the ruby R line (He & Clarke, 1997), colorless sapphire (Elen & Fritsch, 1999) and diamond uv light transmission (Lipatov et al 2010), filtered ruby uv luminescence, etc., are therefore not detectable. The method is beneficial to improving the performance of the light source and deeply learning the precious stone material, and is hopeful to test more new information of the precious stone material by adding new functional modules, combining different modules and the like.

The smart phone is a very mature product at present, and a camera for image and video acquisition has excellent performance, and a matched image and video optimization algorithm is stable and has outstanding effect, so that various fine signals can be captured; the high-resolution large screen is suitable for displaying various detection phenomena; the data transmission, storage and operation costs are reduced, so that the precious stone detection data processing and cloud data operation service connection by using the mobile phone are possible; the mobile phone is also an ideal and convenient tool for data sharing and data interconnection.

The main gem material parameters which can be tested and collected by the device of the invention are shown in table 1.

Table 1 new table of precious stone test parameters obtainable by different functional module combinations

The main precious stone material parameters that can be tested and collected mainly comprise two types: firstly, the material parameters which can be tested by the traditional conventional precious stone detecting instrument but cannot collect data are as follows: polychromatic, absorption spectrum (visible range), white light color filter (phenomenon detected by chalcos under color filter), extinction characteristics (stone extinction observed under mono-, cross-, and cone-polarization), and ultraviolet fluorescence (typically fluorescence pattern under excitation of 254nm, 365nm ultraviolet light source); secondly, the precious stone material parameter that traditional precious stone detecting instrument can't test: fluorescence polychromatic properties, fluorescence spectra, fluorescence color-filtered images, polarized absorption spectra, polarized fluorescence color-filtered images, polarized fluorescence images, and ultraviolet light transmittance. Both types may share a hardware test module.

The polychromatic property, absorption spectrum, white light color filtering, extinction characteristic and ultraviolet fluorescence are tested by the polychromatic property test module, the spectroscopic test module, the color filtering test module, the extinction characteristic test module and the fluorescence test module 1200 respectively. In specific use, the corresponding test module is rotated to the test position (i.e., between the sample stage 1102 and the electrodeless zoom lens 1300) by the turntable 1210.

Ultraviolet light transmittance is tested by using an ultraviolet light transmittance testing module. The principle of utilizing ultraviolet light transmittance detection to analyze the precious stone material is that ultraviolet light is easily absorbed by the material, and the same precious stone material grown by different precious stone types or different causes (such as basalt type, marble type and other different geological causes; high temperature and high pressure method, pulling method and other different artificial crystal growth methods) forms absorption edges at different wavelength positions of ultraviolet energy or forms absorption bands at different positions. Because the common mobile phone camera can not sense ultraviolet energy, the ultraviolet light transmittance test module designed by the invention utilizes the photosensitive fluorescence sheet to convert an ultraviolet light source which can penetrate through a precious stone material into visible light so as to acquire information by using the mobile phone camera. The gemstone material which can penetrate through ultraviolet light energy, and the whole light-sensitive fluorescence sheet emits light during the test; the gemstone material which is not transparent to ultraviolet light energy leaves a non-photosensitive area which is consistent with the outline of the gemstone material on the photosensitive fluorescence sheet; the precious stone material with certain permeability to the ultraviolet light source leaves a weak photosensitive area which is consistent with the outline of the precious stone material on the photosensitive fluorescence sheet.
