ABSTRACT:
A gyro of the type having a multimode optical fiber loop in which light propagates in both directions before being recombined, together with a device constituting a phase conjugate "mirror", wherein the device is a double phase conjugate "mirror" and is disposed in the loop so that the light reaches said device from both sides thereof, with the incident light at each side of the device serving as a pumping wave for phase conjugation of the incident wave arriving at the other side of the device.
