Abstract
An interferometric system with multi-axis optical fiber and a method for processing an interferometric signal in such a system, the multi-axis interferometric system includes a light source (); a plurality of N optical-fiber coils (), a first optical separation element () capable of splitting the source beam () into a first split beam () and a second split beam (); shared phase-modulation element (); a photodetector () and a signal-processing system (). The N optical-fiber coils () are connected in parallel, the coils having respective transit times T, T, . . . TN that all differ from one another, and the signal-processing system () is capable of processing the interferometric signal () detected by the shared photodetector () as a function of the respective transit times in the various coils.
