Abstract

The authors use a fiber sensor integrated monitor (FSIM) as a fully functioning system to characterize the temporal response of a surface-relief fiber Bragg grating (SR-FBG) to temperature heating above $1000°\text{C}$. The SR-FBG is shown to have a rise time of about $77\mathrm{ms}$ for heating and a fall time of about $143\mathrm{ms}$ for cooling. The FSIM also provides full spectral scans at high speed that can be used to gain further insights into the temperature dynamics of a given system.
