摘　　要：提出了一种新型的光纤光栅(FBG,Fiber Bragg Grating)温度传感器封装技术。该传感器使用特殊的工艺将光纤光栅封装在涂覆有聚酰亚胺胶的凹槽基底材料上,基底材料也采用聚酰亚胺材料,该方法提高了传感器的灵敏度和可靠性。在40-120度的温度环境下,对这种新型光纤光栅温度传感器反射光谱反复进行了试验,并与陶瓷材料封装的光纤光栅温度传感器进行了比较,结果表明该新型传感器具有良好的响应特性。this paper proposes a new kind encapsulation technology of the temperature sensor of optical Fiber Grating （FBG, Fiber Bragg Grating）. The sensor makes fiber grating sealed in the basement material that coatings special organic polymer. The basement and polymer use the same material,this method enhances sen- sitivity and reliability of the sensor. In the 40 - 120 degrees temperature environment, we do many experiments about spectral reflectance to this new type of fiber Bragg grating temperature sensor, and compared with the fiber Bragg grating temperature sensor of ceramic material, the result shows that the new sensor has good response.
