Abstract

Principle, structure design, and experimental setup of a fiber Bragg grating (FBG) sensor with a simple signal detection method for demodulation of resonance wavelength shift of the FBG are introduced, which uses a cascade self-demodulated fiber Bragg grating pair attached respectively on the upper and lower surface of a pendulum-type cantilever element instead of a twice reflection FBG pair structure for both parameter sensing and wavelength shift signal demodulating. In addition, crosssensitivity effect of FBG-based sensor automatically solved due to a differential signal process method. With this demodulation method, current, and vibration measurement experiments are carried out. Experimental results indicate that current measurement error of ±1mA can be obtained within the whole range from 0 to 400mA, vibration measurement are also obtained based on the present experiment setup. Keywordsfiber Bragg grating sensor; current measurement; gravity pendulum; electromagnetic force
光纤光栅传感器的简单解调方法
介绍了一种光纤布拉格光栅(FBG)传感器的原理、结构设计和实验设置,该传感器采用一种简单的信号检测方法,用于解调光纤布拉格光栅的共振波长移,该传感器采用一种串级自解调光纤布拉格光栅对,分别连接在摆式悬臂元件的上下表面,代替了两次反射的光纤布拉格光栅对结构,用于参数感知和波长移信号的解调。此外,采用差分信号处理方法,自动解决了fbg传感器的交敏效应。利用这种解调方法,进行了电流和振动测量实验。实验结果表明,在0 ~ 400mA的整个测量范围内,电流测量误差为±1mA,并在此基础上进行了振动测量。关键词光纤光栅传感器;当前的测量;重力摆;电磁力
