Claim 0:
1. A fiberoptic ring interferometer system comprising:
at least two broadband light sources of substantially different center frequencies;
at least two light detectors;
at least two light beam splitters;
at least two light depolarizers;
at least two reference coils of optical fiber;
at least two bidirectional Wavelength Division-Multiplexers; and
a single fiberoptic sensing extension carrying light from said two broadband light sources;, the system being configured such that a corresponding light beam from each broadband light source of the at least two broadband light sources can travel through a corresponding light beam splitter of the at least two light beam splitters, where each light beam can be split into a corresponding counterpropagating light beam pair, each counterpropagating light beam of each counterpropagating light beam pair being configured to travel through a corresponding reference coil of the at least two reference coils, a corresponding bidirectional Wavelength Divisions-Multiplexer of the at least two bidirectional Wavelength Division-Multiplexers, the single fiberoptic sensing extension and a corresponding light depolarizer of the at least two light depolarizers, to a corresponding light detector of the at least two light detectors.
