Abstract
A novel double fiber Bragg grating(FBG) strain sensor configuration is presented. Temperature compensation method is based on double FBG moored on a rhombus frame. Through the theoretical analysis, the relation between relative shift of Bragg wavelength and the strain applied on the sensor is obtained, and the analytical expression of strain sensitivity coefficient is also given. The experiment results show that: in the strain range of 0~0.8 mm, the relation between the relative shift of Bragg wavelength and applied strain is linear, and the dispersion of double FBG wavelength at the range of -25℃~60℃is 0~0.002 nm. The strain sensitivity of the displacement sensor configuration is 0·171 nm/με, and is nearly twice than that of single FBG sensor.
