ABSTRACT:
A three-axis fiber-optic interferometer as applicable in particular to a gyrometer comprises three optical fibers forming rings disposed along three different axes. The three optical fibers are fed by a light beam emitted by a single source. A single interference photodetector receives the light beam after transit through the different fibers. Coupling devices couple the second fiber to the first fiber and the third fiber to the second fiber.
