Abstract
A gyroscope comprising a source for emitting a light beam, an optical fiber loop in which the light propagates in both directions, a dual phase-conjugate mirror disposed in said loop in such a manner that light reaches said mirror from both sides thereof, recombination means for recombining the light which has propagated round the loop, and detector means for detecting the recombined signal, wherein the loop includes a monomode fiber that does not conserve polarization and wherein depolarization means are disposed between said fiber and the phase-conjugate mirror, on either side thereof.
