Study on non-contact Fiber Bragg grating vibration sensor
This article have presented a non-contact vibration sensor based on FBG sensor, and used it to monitor the vibration of rotating shaft. In this article, we described the principle of the sensor and made an experimental analysis. The analysis results showed that the sensitivity and linearity of the sensor were -1.5pm/um and 4.11% respectively within a measuring range of 2-2.6mm. When the sensor was used to monitor the vibration of the rotating shaft, the vibration signals and the critical speed measured were the same as that obtained from the eddy current sensors. This indicated that the sensor could be effectively used for non-contact measurement of vibration of rotating shaft, and fault monitoring and diagnosis of rotating machinery.
