    • The present invention relates to an interferometric system with multiaxial optical fibre and a method for processing an interferometric signal in such a system. In particular, the invention relates to a multiaxial interferometric system comprising a light source (1); a plurality of N coils of optical fibre (11, 12), a first optical separation means (3) capable of splitting the source beam (100) into a first split beam (140) and a second split beam (240); shared phase-modulation means (4); a photodetector (2) and a signal-processing system (800). According to the invention, the N coils of optical fibre (11, 12) are connected in parallel, the coils having respective transit times T1, T2, … TN that all differ from one another, and the signal-processing system (800) is capable of processing the detected interferometric signal (720) by the shared photodetector (2) in accordance with the respective transit times in the various coils.
