摘要
验钞机主要利用红外射线、紫外射线及磁性对钞票进行研究分析,并由此判别钞票的真伪。真钞的磁性分布、红外穿透及红外油墨吸收反射都具有一定的规律,而伪钞要么只具有某一方面规律要么不具有任何规律。因而可以针对这种特性设计验钞机。本文主要讲述如何利用三类红外光电管对钞票的特性进行分类研究,从而区分钞票的真伪,结果证明这些方法是确实可行的。
Bill detect machinery analyses and studies money by infrared ray, ultra - violet radiation and magnetism. Then differentiate the true and false of the bill. The true bill have the rules in magnetism distributing, infrared penetrating and infrared printing ink reflecting. But counterfeit money have only one of these laws or have not any one. So we could design bill detect machinery by aiming at these characteristics. How to use infrared photoelectric cell to distinguish the true and false of the bill are narrated ,results prove the method is feasible.
