Infrared detection system based on MEMS thermopile sensor

In order to realize recognition of moving and stationary states of long distance infrared target,infrared detection system based on thermopile sensor is designed.The system comprises a ladder analysis (GRIN) lens,MEMS thermopile sensor,signal conditioning circuit,data acquisition circuit and recognition algorithm.Detection results show that with the same optical path system,it can achieve more distance than the system of pyroelectric,realize the recognition of dynamic and static targets,and based on the difference in detecting target temperature and radiation area,it can achieve the distinction between human,vehicle and other infrared targets.This proposed method provides a new solution for the detection and recognition of infrared targets.
