本文综述了近年来光纤恶劣环境传感器在燃煤电厂运行工况监测、煤制合成气关键气体组分原位检测等高温恶劣环境传感领域的研究进展。本文介绍的传感器包括一步激光微加工的小型直列光纤法布里-珀罗干涉仪（FPI）、长周期光纤光栅（LPFG）和可控CO2激光辐照的光纤直列芯包层模式干涉仪（CMMI）。介绍了它们的工作原理、制造方法以及在高温高压共存恶劣环境下测量各种物理和化学参数的应用。
This paper summarizes our recent research progresses in developing optical fiber harsh environment sensors for various high temperature harsh environment sensing applications such as monitoring of the operating conditions in a coal-fired power plant and in-situ detection of key gas components in coal-derived syngas. The sensors described in this paper include a miniaturized inline fiber Fabry-Perot interferometer (FPI) fabricated by one-step fs laser micromachining, a long period fiber grating (LPFG) and a fiber inline core-cladding mode interferometer (CMMI) fabricated by controlled CO2 laser irradiations. Their operating principles, fabrication methods, and applications for measurement of various physical and chemical parameters in a high temperature and high pressure coexisting harsh environment are presented.
