利用陶瓷封装技术，设计并制作了多只光纤光栅温度传感头，测试了探头的测试灵敏度、稳定性、重复性、响应速度等多个参数受封装加工形式的影响。实验采用恒温水浴装置，在36℃~45℃的温度范围内使用了中心波长位于1 540 nm和1 550 nm附近的多只布拉格光纤光栅进行了对比测量。实验结果表明：陶瓷封装布拉格光纤光栅的波长/温度响应度为9.815 pm/℃，测量标准偏差为0.08 ℃。
Abstract
Adopting the ceramic packaging technology, we designed and produced several fiber Bragg grating (FBG) temperature sensor probes to test the sensitivity, stability, repeatability, speed of response of the probe and other parameters affected by the packaging processed form. The parameters of FBG were analyzed by a water bath apparatus with constant temperature to calibrate the thermal response of FBG with the central wavelength around 1 540 nm and 1 550 nm, and the temperature increased from 36℃ to 45℃. The experiment results showed that the scalar efficiency of the FBG probe with ceramics package was 9.815 pm/℃ with standard deviation of 0.08 ℃.
