摘　　要：本文报道了一种新颖的光纤光栅高灵敏度温度传感封装及一种高分辨率光纤光栅波长检测方法,波长变化分辨率可达0.002nm,应变分辨率为1.7με;光纤光栅增敏封装后温度灵敏性可提高7倍多,温度分辨率为0.03℃.A novel technique for coating fiber Bragg gratings to improve its sensitivity and a novel method to measure the reflective wavelength of the grating with high resolution are reported. The wavelength resolution and the strain resolution of this novel sensor are 0.002nm and 1.7μ ε respectively. The temperature sensitivity of the sensor is seven times higher than that of a monomode fiber with Bragg grating. The resolution of temperature measurement is 0.03℃.
