摘要
The present patent application discloses an optical fiber interferometric rate gyro using the SAGNAC effect particularly adapted to the measurement of low rotational speeds comprising, between the radiation splitting and recombining device which directs two waves simultaneously towards the two ends of a single mode wound optical fiber and recombines the two waves emerging from the fiber after travelling in opposite directions at each of the two ends of the fiber, a splitter associated with a detector picking up a fraction of the wave emerging from the corresponding end, the speed measurement being obtained from signals from these detectors and from the signal from a detector picking up the radiation resulting from the recombination of both waves.
