Abstract: An interferometric resonator optical gyroscope includes an optical frequency comb generator configured to generate an optical frequency comb. Optical signals representative of the optical frequency comb pass through an optical resonator in different directions, and a rotation rate is determined based on the extent of interference between the optical signals. Parameters of the optical frequency comb generator can be controlled by a control servo based on an intensity of the optical signals after propagating in the optical resonator. Utilizing an optical frequency comb generator reduces the bias error during gyroscope operation.
