| 摘 要： | 采用拉曼光谱作为分析手段,以近红外激光785 nm波长激发,获得了真、假一百元人民币在固定人像水印、全息开窗安伞线、隐形面额数字和光变油墨数字等处的谱图.发现真币与假币的谱图有明显差别,而且不同来源的假币的拉曼光谱也存在着可分辨的差异.研究表明,利用拉曼光谱的分子指纹和微区分析能力,不仅对伪造、变造人民币的识别有重要价值,而且可以分辨不同来源的假币. |

| Abstract: | Raman spectra of real and counterfeit RMB 100 banknotes excited by an infrared laser with wavelength of 785 nm were obtained in the portrait watermark,security thread,latent image for the face value and OVI printing features.Difference between the spectra of real and counterfeit RMB banknotes was found.Meanwhile,difference of counterfeit banknotes from different counterfeiters was also observed.The study shows that Raman spectroscopy could be a potential tool not only for the identification of counterfeit and altered RMB,but also for the sources of the counterfeit RMB. |
| Keywords: | spectroscopy spectroscopic analysis identitication of forged banknotes Raman spectroscopy intrared laser |
