Abstract :
The subject of this work is a demodulation system in fibre optic distributed sensor. The system uses digital demodulation with application of fiber optic 3/spl times/3 coupler. Digital processing is used to linearly reproduce dynamic phase signals in fiber interferometer as a distributed sensor. The sensor is constructed as an unbalanced fibre optic Michelson interferometer.
