ABSTRACT:
Apparatus for multiplexing fiber-optic sensing interferometers, which apparatus comprises at least one optical source, a plurality of matched interferometers connected to the optical source and each containing a phase modulator having a unique identifying characteristic, a network of fiber-optic sensing interferometers each containing a path-length difference, at least one detector, and interconnections provided between the matched interferometers, the network of fiber-optic sensing interferometers and the detector, the path length difference in each fiber-optic sensing interferometer being approximately matched to a path length difference in its associated matched interferometer, and the interconnection means between the matched interferometers, the network of fiber-optic sensing interferometers and the detector being such that there is no more than one signal on the detector having the same unique identifying characteristic associated with one of the phase modulators.
