Counterfeiting method and system utilizing combined ultraviolet laser Raman and fluorescence spectrum

Abstract

The invention relates to a counterfeiting method utilizing a combined ultraviolet laser Raman and fluorescence spectrum, comprising the step of simultaneously measuring a Raman spectrum and a fluorescence spectrum of a sample material, wherein the fluorescence excitation spectrum and the Roman spectrum of the sample are detected by utilizing a spectrograph while irradiating the sample by utilizing ultraviolet laser; after the step is finished, comparing the Roman spectrum and the fluorescence spectrum of the obtained sample material with a spectrum of a product material with the same category in a product material combined ultraviolet laser induction Roman and fluorescence spectrum network database; and finally judging the truth or falsity of the measured material. The spectrum data is acquired by utilizing a computer and then transmitted to a center server by a network, and in the center server, the Roman spectrum and the fluorescence spectrum are compared with the spectrum of the product material with the same category in the product material combined ultraviolet laser induction Roman and fluorescence spectrum network database. The invention can completely solve the problem of the truth or falsity judgment of goods by utilizing the uniqueness of the ultraviolet laser induction Roman and fluorescence spectrum of the material.

Description

Technical field: [0001] The present invention relates to the field of physics, in particular to spectral measurement technology, in particular to an anti-counterfeiting method and system using ultraviolet laser Raman fluorescence combined spectrum. Background technique: [0002] Anti-counterfeiting technology is a technical means for identifying authenticity and preventing counterfeiting and counterfeiting. It is widely used in various fields, especially in the fields of cultural relics, jewelry, clocks, cosmetics, luggage and other luxury goods. Anti-counterfeiting technologies are increasingly being used in fields where chips and medicines are counterfeited and there are many infringements. [0003] There are generally three ways to anti-counterfeit goods: the first way is packaging anti-counterfeiting, such as disposable wrapping paper or packaging film, anti-counterfeiting paper or anti-counterfeiting film with anti-counterfeiting features; if it is bottled, for example,...
