荧光检测技术在复点机辨伪中的应用

The Application of Fluorescence Measurement Technology in Counterfeit Recognition with Bank-Note Counting Machine

根据荧光检测技术的原理,在实验室对各种真钞、伪钞进行荧光测试、光谱分析,发现当紫外线照射钞票表面时,真钞、伪钞表面的物质被入射的紫外线激发,发射出不同波长、不同强度的荧光,文章中的复点机正是利用这一光谱范围内荧光强度的差异来进行辨伪的,该方法简便、识别率高,已运用到复点机的生产中。

Based on the theory of fluorescence measurement technology, various true and counterfeit banknotes were tested via fluorescence and analyzed via spectrum in this paper, it was found that when the banknote was inspired by the ultraviolet radiation, the true or counterfeit ones would demonstrate different fluorescence intensity and spectrum. We use these characteristics to recognize the banknote and counterfeit banknote in the bank-note counting machine.
