摘要: A resonator fiber optic gyroscope (RFOG) is provided. The RFOG includes a coil, first and second lasers, phase modulators, common modulator. laser generates CW input light for propagation in the direction of coil. CCW modulator modulates with modulation frequency f 1 = (n+0.5)*FSR. 2 (m+0.5)*FSR so that overlap major sidebands avoided. amplitudes modulators substantially suppress optical carrier components light. configured to modulate amplitude.
