Abstract
Wavelength division multiplexing (WDM) offers a potentially powerful technique for use within single optical fibre sensor systems and multiple sensor networks. The paper commences with a short review of the spectrally modulated and dual wavelength referenced, intensity modulated optical sensors. A WDM system employing multimode fibre and LED sources is then discussed. This is followed by descriptions of particular WDM optical sensor system developments in order to illustrate the approaches currently adopted. Potential network topologies for WDM multiple sensor networks are then introduced, with some description of the major implementational constraints to provide an indication of possible future developments.
