Spatially dynamic temperature monitoring of Hydrogen flame by telecom fiber using OFDR

Abstract

The distributed temperature profile of hydrogen flame based on OFDR was experimentally demonstrated for the first time. Spatially dynamic temperature field of H2 flame was monitored via a telecom fiber withstanding the flame over 30 seconds at 1000 °C. Higher temperature measurement beyond 1100 °C is possible with a fast system response time (<1s).
