摘要
介绍线性斜边滤波器在光纤光栅传感系统中的应用,根据斜边滤波器波长解调方案的工作原理,主要介绍一种利用斜边滤波器的光纤光栅解调技术.实验采用1530/1550 nm的斜边滤波器对单点光纤光栅应变和温度进行解调,结果表明该解调系统具有0.01 nm的波长分辨力.该系统结构简单,易于解调.
The fiber bragg grating sensor system with tilt filter is introduced. A demodulation technique of fiber bragg grating is proposed based on the operating principle of wavelength demodulation scheme of tilt fiber coupler. In experiments, demodulation for signal point fiber bragg grating strain and temperature is carried by use of 1530/1550 nm tilt filter. The result shows that the demodulation system has a wavelength resolution of 0.01 nm. The system is simple and easy to demodulate.
