摘要
通过设计一种用于检测纸币上红外上转换材料的光电传感器,研究这种光电传感器的工作原理、结构以及信号处理电路。该传感器具有体积小、抗干扰能力好等特点,对红外上转换材料在防伪技术上的应用提供了有力的检测手段,同时,这种传感器易于安装在自动点钞机上,有很好应用前景。
A opto-electronics sensor for detecting the infrared up-conversion materials on bank note has been designed. In the text, the principle, the structure and the signal processing circuit of the opto-electronics sensor is introduced. The senor has many advantages, such as small cubage, high anti jamming ability, etc. It also provide a easy way to use infrared up-conversion materials in anti-counterfeiting technology. This sensor can be easily and widely used in detecting banknotes.
