Paper Abstract

We describe an instrumentation system which provides the capability to monitor a large number of Bragg gratings using a common source and a scanning narrowband filter. The system described has the capability to monitor 12 FBG sensors along each of 5 fibers for a total of 60 sensor elements. We demonstrate the use of this system to address multiple sensors embedded in and attached to a quarter scale bridge span.
