【摘要】 光纤Bragg光栅虽已应用于传感领域,但传感信号快速准确地解调仍然是限制其广泛应用的主要问题。本文提出了一种基于匹配滤波法的FBG传感器解调方案,利用基于ARM的控制系统控制精密电动位移台的运动来驱动等强度悬臂梁实现匹配滤波,通过采集电路及核心处理器进行解调运算,实现了对传感光栅所处环境参量的检测。更多还原

【Abstract】 Although Fiber Bragg Grating(FBG) has been widely applied in the sensing field,how to demodulate the sensing signal,precisely and quickly,is still the main problem of limiting its wider application.Demodulation technology of FBG sensing system based on matching filtering FBG was presented in this paper.Running mode of motorized precision translation stages controlled by ARM drived the equi-intensity cantilever beam(EICB) to realize matching filtering,and the demodulation operation was processed by the signal acquisition circuit and the MCU.The system can successfully realize the diction of the environmental variables.更多还原
