Abstract

We report an experimental study of a SMS fiber sensor for simultaneously measuring both displacement and temperature. By measuring both central wavelength spectral shifts and peak power variations, displacement and temperature can be independently determined with a demonstrated sensitivity to displacement of 0.62 μm and a temperature sensitivity of 1 °C by using a typical OSA which has a wavelength resolution of 10 pm and power measurement resolution of 0.01 dB.
用单模-多模-单模(SMS)光纤结构同时测量位移和温度
本文报道了一种同时测量位移和温度的SMS光纤传感器的实验研究。通过测量中心波长光谱位移和峰值功率变化,可以独立确定位移和温度,使用波长分辨率为10 pm,功率测量分辨率为0.01 dB的典型OSA,对位移的灵敏度为0.62 μm,温度灵敏度为1°C。
