Paper Abstract

A technique for temperature compensation in fiber grating vibration sensor is reported. By special design, it causes reversed strain on two FBGs and has temperature effects cancelled. After discussion about the factors affecting the sensitivity and the width of frequency band, it is experimentally proved that the total variation in wavelength difference within temperature of -15 ~ 50°C is nearly 0. When the input vibration frequency is up to 800Hz and the drive power is as low as 2mw, the output waveform is still distortionless.
