提出了一种基于S型光纤锥Mach-Zehnder干涉仪（SFT-MZI）嵌入光纤布拉格光栅（FBG）的超紧凑光纤传感器，并进行了实验验证。实验结果表明，SFT-MZI的光谱灵敏度为-48.56842 nm/N （~54.97 pm/με）和14.71 pm/°C， FBG的光谱灵敏度为1.30588 nm/N和10.13 pm/°C。SFT-MZI表现出与FBG相反的力响应，对力高度敏感。传感器矩阵计算的力和温度与实验中的实际力和温度吻合较好。
An ultracompact optical fiber sensor based on an S fiber taper Mach-Zehnder interferometer (SFT-MZI) embedded in fiber Bragg grating (FBG) is proposed and experimentally demonstrated for simultaneous force and temperature measurement. Experimental results show distinctive spectral sensitivities of -48.56842 nm/N (~54.97 pm/με) and 14.71 pm/°C by the SFT-MZI, and 1.30588 nm/N and 10.13 pm/°C by the FBG. The SFT-MZI, exhibiting an opposite force response as compared with that of the FBG, is highly sensitive to force. The force and temperature calculated by the sensor matrix agree well with the actual force and temperature in the experiment.
