Abstract： An active temperature compensated fiber Bragg grating (FBG) vibration sensor with a constant section cantilever beam is proposed for the simultaneous measurement of temperature and vibration, and the sensor is verified by a temperature compensation feedback system. The high-temperature vibration sensor is composed of a quartz cantilever beam and a femtosecond Bragg grating. The feedback control demodulation system of active temperature compensation can adjust the laser wavelength to stabilize the grating offset point and realize simultaneous measurement of temperature and vibration. On this basis, the performance of the sensor is tested and analyzed within the range of 20-400 ℃ by setting up a high-temperature vibration test system. The experimental results show that the sensitivity of the sensor is about 132.33 mV/g, and the nonlinearity is about 3.33%. The sensitivity between the laser wavelength and temperature is about 0.013 07 nm/℃. In addition, the active temperature compensated fiber Bragg grating vibration sensor has the advantages of a simple structure, stable performance, easy demodulation and high sensitivity. Moreover, the sensor can achieve high temperature vibration signal monitoring and has good practical application value.
