| Abstract: | A novel fiber Bragg grating(FBG) for large current sensor configuration based on GMM is presented.The impact of temperature on GMM and the problem of temperature-strain cross-sensitivity of the sensor is solved.A temperature compensation scheme is designed.The experimental results show that in the range of 0~90 ℃,the relation between the dispersion of two FBGs Bragg wavelengths and current is linear.The result indicates the structure can achieve the effect of temperature compensation and solve the impact of cross-sensitivity and has economical benefits. |
