Original Technique for Residual Amplitude Modulation Reduction in RFOG

We report an original technique for reducing the residual amplitude modulation in a resonator fiber optic gyroscope using fibered components. We illustrate its effectiveness and compare it to the classical method used to control the RAM by checking the photodiode signal spectrum and measuring the free spectral range of the cavity with both methods.
