| 摘 要： | 使用上转换材料可有效地将红外射线转换为可见光。对于确定的上转换材料，当 选用恰当的激发光源进行激发时，可得到唯一确定的转换光谱；使用上转换材料将红外射线转 换为可见光这种技术，有很好的私密性，可安全、有效地用于防伪鉴真识别技术中。本文在光 学频率上转换理论上，建立了弱光光谱检测系统，使新型光谱发射器件、专用光电接收器件、 光德波器件和光电混合集成模块、专用弱光信号处理及补偿芯片等元件实现优化组合和匹配。

| Abstract: | Upconversion material can convert infrared radiation into visible light. As to the upconversion material assured, the single and definitive conversion spectrum can be got when the adapted optical pumping source is selected. This type of upconversion material that convert infrared radiation into visible light has good primacy. It can be used in the technology of identification saly and validly. On the optical frequency upconversion theory, a weak light signal type recognition system has been founded, which makes the elements such as the spectral emitter, the special photoelectric receiver, the optical filter, the photoelectric hybrid integrated module, the special weak light signal processing and compensating unit optimum designed. |
