Paper Abstract

In order to maintain the normal running of economy in China, anti-counterfeiting detection of paper currency has been an important technology in the coinage company and the bank, but the detection using spectrum for Chinese paper currency anti-counterfeiting has not been applied in China. A real-time detection method, with broad spectrum including ultraviolet and infrared wavelengths, is proposed in this paper, which achieves the purpose of anti-counterfeiting by using anti-fake properties of paper currency's coating surface, through different lights stimulation the full spectrum light irradiation on currency surface, with its reflection spectrum detected by spectrometer. The proposed method has such advantages as high technology, high detection precision and easy to identify, and has been applied to a practical system, which satisfies the real-time requirement.
