Optical Fiber Sensors for Harsh Environment Monitoring

Abstract

This paper summarizes our recent research progresses in developing optical fiber harsh environment sensors for monitoring the operating conditions of 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 CO 2 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. © 2010 ASCE.
