A Novel Fiber Bragg Grating Temperature Compensated Strain Sensor

This paper analyzed the strain-temperature crosssensitive characteristic of optical fiber Bragg grating(FBG)theoretically,designed and made a novel FBG strain sensor.It has a temperature-compensated function,and it improves the effect of being sensitive to strain.To a certain extent,this sensor overcame the traditional temperature-compensated methods easy to have a creep and aged phenomenon.The experimental results show that the sensor realized the temperature sensitivity reduces to 1/10 before the seal,and the strain sensitivity increases to 1.4pm/με over the temperature range from -10℃ to 50℃.
