Paper Abstract

A fibre-optic system for monitoring bridges with multiplexing support for >64 grating-based strain sensors is presented. Differential wavelength-demultiplexing controlled via LabView™ results in a system with 1με resolution, in-built temperature-referencing and readiness for commercial field-trials.
