Re-configurable, multi-channel, high-speed FBG strain sensing system for vibration analysis in oil risers

摘要

Eight re-configurable, synchronized resonant cavity time-division-multiplexed FBG sensor interrogators provide 16,800 high-resolution measurements-per-second from 280 axially embedded strain sensors, for the analysis of vortex-shedding-induced vibration and bending in a composite oil riser pipe.
