Abstract
A stimulated Brillouin scattering (SBS) gyroscope comprises a resonator; a first laser in communication with the resonator and configured to emit a first optical signal propagating in a first direction, the first optical signal producing a first SBS signal counter-propagating in a second direction; a second laser in communication with the resonator and configured to emit a second optical signal propagating in the first direction, the second optical signal producing a second SBS signal counter-propagating in the second direction; a third laser in communication with the resonator and configured to emit a third optical signal propagating in the second direction, the third optical signal producing a third SBS signal counter-propagating in the first direction. At least one photodetector is coupled to the resonator and receives the SBS signals, which are combined in the photodetector to produce electrical signals that include rotational rate information encoded in frequencies of the electrical signals.
