Abstract

The potential of large scale fibre optic sensor arrays for distributed and real time monitoring of engineering structures is discussed. It is shown that novel spatial multiplexing techniques augmented by special signal processing algorithms, whilst being more robust than systems based on other multiplexing techniques, can also achieve higher multiplexing capacity, measurement speed and cost effectiveness
