摘要
以光学频率上转换检测理论为基础,设计产生特定波长的光发射芯片,用来激发转换材料的表面产生另一个特定波长的光学信号,通过设计专用光接收芯片接收进行检测判决。采用混合集成技术,将光发射芯片、光接收芯片、光滤波片、弱光信号处理系统集成到微型化系统模块中,解决了原有分离器件检测的问题,提高了检测准确度和集成度,可以运用到综合防伪检测系统中。
Based on the theory of upconversion material converting infrared radiation into visible light,the light emitting chip which emits light at certain wavelength is developed to excite another single and definitive signal light from the upconversion material,and the signal will be detected by the special optoelectronics receiver. By the hybrid integrating approach,the elements above are integratee, the optical filter and weak light signal processing into a single module to solve the problem of separated detection system, enhance the exactness and integration of this module which can be adopted in a comprehensive detection system.
