钞票多光谱光电信号的分析

Analysis of photoelectric signal about multi-spectroscopic of banknote

文中介绍了钞票的光反射和透射机理及钞票的光反射和透射检测技术。通过对其机理的研究和对比实验 ,找到真假钞票在光透射方面的特性差异 ,有针对性地利用其特性研制有关检测电路及光反射和透射检测系统 ,可实现对钞票的检伪和识别。该技术可直接用于金融器具的制作 ,提高金融器具对钞票的检伪和识别 。

In this paper, the theoretical study and measured technique for the banknote of the reflection light and the transmission light are introduced. After the contrast experiment, the characteristic differences of the true and false banknotes are discovered. The check circuit and check system of the transmission and reflection light were developed with making use of the characteristic difference in the pertinence. The banknote was checked and recognised with the check system. The technology was directly used to doing of finance instrument. The recognizing technology and falsing technology of the banknote will be advanced in the finance instrument. The technique is very applicable.
