Abstract
The interferometric laser gyrometer according to the invention comprises a laser source, a wound monomode optical fibre an a detector, the optical coupling between the source and the two ends of the optical fibre in order that these two ends receive equal parts of the light emitted by the source contro-propagating in the fibre and the optical coupling between these two ends and the detector being effected by wave guides integrated on an electrooptical substrate at which the two ends of the fibre are rigidly coupled.
