This article briefly discussed the most foundational principles of modulation method applied to the input light in a resonator fiber optic gyro. Lorentz formula was employed to describe the transfer function of the fiber resonator, so the system's mathematical model in frequency field could be built according to the feature of the input signal. The result and related emulating diagrams, as well as the evaluation of some important parameters were given. Finally, a particular operation system scheme was suggested. It is concluded that R FOG has excellent linear working region and potential possibility to improve its performance.
