摘要

本文从理论上分析了光纤光栅(FBG)的应变-温度交叉敏感特性，设计并制作了一种新型的光纤光栅应变传感器。具有温度补偿功能，提高了应变敏感效果。该传感器在一定程度上克服了传统的温度补偿方法容易产生蠕变和老化现象。实验结果表明，在-10℃~ 50℃的温度范围内，传感器实现了温度灵敏度降低到密封前的1/10，应变灵敏度提高到1.4 pm/ epepv。

A Novel Fiber Bragg Grating Temperature Compensated Strain Sensor

This paper analyzed the strain-temperature cross sensitive 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 1.4 pm/uepsiv over the temperature range from -10degC to 50degC .
