PROBLEM TO BE SOLVED: To provide a resonator fiber optic gyroscope with a lower cost and/or a smaller navigation grade.SOLUTION: A resonator fiber optic gyroscope comprises: a first light source 112 configured to produce a first light beam having a first frequency comb spectrum; and a second light source 114 configured to produce a second light beam having a second frequency comb spectrum. A first optical filter 116 is configured to pass a first frequency comb portion of the first frequency comb spectrum, and the first frequency comb portion has a free spectral range value. A second optical filter 118 is configured to pass a second frequency comb portion of the second frequency comb spectrum, and the second frequency comb portion has a free spectral range value. The second frequency comb portion is spectrally separated from the first frequency comb portion. |
