Interferometric optical fibre sensors have a great potential in structure monitoring because of their high resolution, huge dynamic range and attractive nature of optical fibre itself, such as low cost, compact size, lightness, flexibility, strength and immunity to electromagnetic interferences and chemical corrosion. However, interferometric signals are relatively difficult to interrogate. Some special provisions results in a large number of optical fibre devices in the sensor system, particularly in applications like structure monitoring, where many sensors are required to be multiplexed into an integrated sensing network. The characteristics of these discrete devices are mostly oposite to that of the fibre itself. They are relatively expensive, bulky, heavy, fragile and may even contain electrically active or mechanically moving parts. This prevents interferometric sensors from fulfilling their potential.The existing multiplexing techniques are not successful in reducing the number of devices per sensor in the network. The aims of the proposed research are to develop a new multiplexing technique, namely digital spatial domain multiplexing. Its main feature is to use more fibres in exchange for a substantial reduction of discrete devices in a large scale interferometric sensor array network. It is expected to significantly increase the multiplexing capacity, reduce built cost and improve maintainability. In particular, the use of this technique for structure monitoring will be evaluated.
