A number of optical and opto-electronic techniques have been developed for the demodulation of inthrferometric fiber optic sensor (IFOS) in recent years. Many of these techniques allow passive operation of the actual sensor, and may find application in certain IFOS multiplexing topologies. This paper will briefly review IFOS demodulation techniques, highlighting which are applicable to multiplexing, and comparing practical performance features such as sensitivity, bandwidth, dynamic range and linearity. Recent advances in the area of passive demodulation and multiplexing will then be discussed.
