Paper Abstract

We introduce models and realizations demonstrating the feasibility of multimode fiber optic gyroscopes (MFOG). Some solutions to specific problems of MFOG (contrast instability and zero drifts) are described in terms of coupling effects on nonidentical counter propagating modal distributions. Our first experimental results show good correlations between phase and intensity variations under modal coupling effects. We propose a method of detection adapted to MFOG which uses a zero drift stabilization device based on these correlations.
