“…The scale factor is tested and calculated based on equivalent input method [15]. The CCW loop is taken to be the frequency-lock servo loop, namely the selected demodulation of CCW output is used to drive the servo electronics that adjusts the CCW light wave input frequency to match the CCW cavity resonance frequency.…”

A resonator integrated optic gyro (RIOG) employing trapezoidal phase modulation (TZPM) technique is proposed, analyzed, and demonstrated for the first time. This technique can provide more information about the whole gyro system without complicating the light circuit structure, making it possible to compensate the gyro output in real time. The experimental results of the RIOG prototype show that the standard deviation is greatly reduced after compensation, which proves the viability and effectiveness of the TZPM technique. A bias stability of 0.09 deg/s with an integration time of 10 s over 3000 s is achieved, which is, to our knowledge, the best long-term performance that ever been reported in a RIOG based on a silica waveguide ring resonator.

A transmissive resonator optic gyro (TROG) based on silica waveguide ring resonator with improved long-term bias stability is reported in this paper. The modeling of a transmissive resonator used in optic gyro is carried out. The polarization dependence of resonator and the influences of phase modulator's residual intensity modulation on the gyro output are analyzed. The resonator is simulated, designed, fabricated, tested and used to build up a TROG prototype. A bias stability of 0.22°/s over one hour test with an integration time of 10s is successfully demonstrated. No obvious drift has been found from the Allan variance analysis result of a 10000s test data, which means that the TROG prototype has an improved long-term drift characteristic.
