基于荧光光谱分析的钞票识别研究

Study of the banknote recognition based on the fluorescence spectral analysis

文中对钞票在紫外线的作用下激发出的荧光特性进行光谱分析 ,并设计了基于荧光光谱分析的钞票识别的光学系统、光电信号的检测和信号处理系统。荧光光谱分析方法具有灵敏度高、选择性强、式样少、方法简便的特点 。

In this paper, the fluorescence spectral analysis was studied. When the banknote was inspired by the ultraviolet rays, its fluorescence speciality was undertaken deepgoing research. The banknote recognition optical system, the photoelectronic detecting and the signal processing system was designed based on the fluorescence spectral analysis. It is proved that the fluorescence spectral analysis method has high sensitivity. It has small pattern and is strong selective, simple and convenient. It has been used to produce financial instrument.
