Abstract :
The authors report the demonstration of an instrumentation system capable of monitoring a large number of Bragg gratings using a common source and scanning narrowband filter. The system described monitors five arrays of 12 Bragg gratings sensors for a total of 60 sensor elements with μstrain resolution
