Gyroscope fiber-optic interferometric particularly adapted to the measurement of the low speeds of rotation.

摘要

P the invention relates to a gyroscope fiber-optic interferometric using the sagnac effect for the measurement of speeds of rotation. / p & & p & the gyroscope according to the invention comprises, between the device for separation and recombination of the radiation, which makes it possible to steer simultaneously two waves towards the two stiffener of a monomode optical fiber wound and recombining the two waves emerging from the fiber after circulating in opposite directions, and each of the two stiffener of the fiber, a separator associated with a sensor making it possible to pick up a fraction of the wave emerging from the corresponding end, the speed measurement since obtenuea the basis of the signals coming from these detectors and of the signal coming from a sensor sensing the resultant of the recombination of the two waves. / p & & p & application, in particular, the measurement of the low speeds of rotation. / p
