摘要
光纤法布里-珀罗(F-P)微腔传感器具有抗电磁干扰、耐恶劣环境、体积小、精度高等诸多优点,基于光纤F-P传感技术的高温环境物理参量测量得到了研究人员的广泛关注。从光纤F-P干涉原理出发,介绍了F-P多光束干涉原理和光束耦合模型,以及用于干涉光谱信号解调的两种解调技术;讨论了基于光纤F-P传感技术在高温环境下物理参量测量的研究进展。在此基础上,分析了高温环境下光纤F-P传感在新工艺制造技术催生下,向着微型化、批量化制备和多用途化方向的发展趋势。
Fiber-optic Fabry-Perot microcavity sensors have many advantages, such as antielectromagnetic interference, resistance to harsh environments, small size, and high accuracy. The measurement of physical parameters in high-temperature environments based on fiber-optic Fabry-Perot sensing technology has attracted wide attention from researchers. Based on the principle of fiber-optic Fabry-Perot interference, the principles of FabryPerot multibeam interference and beam coupling model, as well as two demodulation techniques for demodulation of interference spectrum signals were presented. In addition, the use of fiber-optic Fabry-Perot sensing technology in high-temperature environments was discussed. The research progress of physical parameter measurement based on the development trend of fiber-optic Fabry-Perot sensing in high-temperature environments toward miniaturization,batch preparation, and multipurpose due to the birth of new process manufacturing technology were analyzed as well.
