Microstructured optical fiber high-temperature sensors

Abstract

At the University of Adelaide and the University of South Australia, we are utilizing the unique optical and material properties of microstructured optical fibers for new and challenging sensing applications. I will present our recent progress in using pure-silica microstructured optical fibers with femtosecond laser ablation fiber Bragg gratings (FBGs) for high temperature sensing up to and beyond 1000°C. In this project we are working with our industry partner, local engineering company SJ Cheesman, to develop multipoint sensors for pyrometallurgical applications.
