This paper presents a novel non contact radial vibration displacement measurement method based on fiber Bragg grating (FBG) sensing technology and introduces the principle and structure of the vibration sensor. The static displacement calibration experiment was carried out to determine linear range and sensitivity of the sensor. Finally, the sensor was used in the dynamic test of a rotating machinery experiment platform and the results show that the measurement method is feasible.
