Study of Transmit & Receive Integrated Optoelectronics Module for Optical Upconversion Anti-counterfeit Detection

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.
