Figure 3.
Variation in temperature measured using reference probes and FBG sensors (both with and without package) during a temperature cycle (from room temperature to 80 °C) for FBG#8 (a) and FBG#10 (b). Variation in the Bragg peak position as a function of the temperature for FOSAS-4 (having PTFE package), FBG#8, FBG#10 (c), and FOSAS-4 all 16 FBGs (d).
