1. A system comprising:

  • a light source configured to produce a multiple-frequency light beam based on an optical frequency comb;

    an optical fiber resonator coupled to the light source, the multiple-frequency light beam based on an optical frequency comb generated by the light source propagating in a first direction within the optical fiber resonator, wherein the multiple-frequency light beam based on an optical frequency comb generates stimulated Brillouin scattering for at least one frequency, wherein the Brillouin scattering generates a stimulated Brillouin scattering light beam containing at least one frequency component to propagate in the optical fiber resonator in a second direction, the first direction being opposite in direction to the second direction;

    at least one servo that controls the frequencies of the optical frequency comb so that a plurality of component frequencies of the optical frequency comb are locked on resonance peaks of the optical fiber resonator in the first direction; and

    a mixer configured to determine a frequency difference between the stimulated Brillouin scattering light beam and the multiple-frequency light beam.
