摘要
提出了采用共焦光学传感头检测红外上转换油墨 (IRink)的上转换弱光信号的方法 ,采用了专门设计的光学元件和检测放大电路 ,实现了红外油墨上转换发光的微弱光检测 ,对不同混合比例红外上转换油墨进行了检测 ,分析了实验结果 其结构简单、取样准确 。
A method of detecting the weak light of up-conversion ink with confocal optical sensor system is proposed in this paper. The properties of the device, such as the sensitivity to the emission light from the up-conversion ink and the characteristics of the special design component, are analysed. The results of detecting the IR ink marks of different mixing ratios have been given.This method of detecting has a simple structure with sampling well and truly. It can realize pocket edition to the detector.
