| 摘 要： | 根据人民币不同防伪部位的红外光穿透特性不同的规律,分析并试验得出照射纸币的红外光的最佳入射光强,并设计了信号处理电路。将红外光透过纸币的光通量转化为模拟电信号,再通过ADC转换成单片机可识别的数字电信号,使用单片机将数字信号记录,并与标准波形特征对比,实现纸币的红外光智能检伪。

| Abstract: | According to the distribution law of transmitted light in different parts of a note when it was irradiated by infrared light,this paper analyzed and worked out the optimal intensity of infrared,and designed a signal processing circuit.The infrared luminous flux penetrating the paper was translated into analogous electrical signal,and then be converted to digital electrical signal which can be identified by SCM.At last,the SCM recorded the signal and compared it with the standard one with waveform characteri... |
