Abstract

In this paper we report the realization of a new version of a multimode fiber optic gyroscope (MFOG). The aim our work is to demonstrate that we can improve the performances of such device by an appropriate choice of its components, in the frame of the compromise low cost/ high performances realization. Our MFOG set up uses 1031 m of step index 50/125 μm multimode fiber in the sensing coil, the first coupler is a standard fused coupler whereas the second one is a micro-optic coupler. The preliminary results show that the observed sensitivity of the prototype is ~0.05 °/sec and the measured dynamic range is ±34°/sec.
