Abstract
In this paper, we proposes a general model for describing and analysing the operation of the multimode fiber optic gyroscope (MFOG). In this model, each fiber gyroscope components is modeled by an electrical field transfer matrix. The output intensity is expressed in terms of the rotation rate and of the components parameters. The simulation results show that performances enhancement can be obtained by employing a symmetrical multimode coupler and low coherent light source.
