摘要

设计并研究了一种基于液晶填充侧孔光纤(SHF)的Sagnac干涉仪温度传感器。液晶的折射率对温度变化很敏感。从而提高了液晶填充sagnac干涉仪的温度灵敏度。最后，可以实现灵敏度高达223pm/°C的温度测量和温度传感。这大约是光纤布拉格光栅(FBG)传感器的20倍。

Optical fiber temperature sensor based on liquid crystal permeable side-hole microstructured fiber

A Sagnac interferometer temperature sensor based on liquid crystal filled side hole fiber (SHF) is designed and studied. Liquid crystal's refractive index is sensitive to temperature changes. Therefore, the temperature sensitivity of the liquid crystal-filled sagnac interferometer is enhanced. Finally, temperature measurement and temperature sensing with sensitivity up to 223pm/°C can be achieved. This is about 20 times that of the Fiber Bragg Grating (FBG) sensor.
