| Description: |
International audience ; The quadrupolar winding of the sensing coil of a fiber-optic gyroscope (FOG) is an essential technique to reduce the thermal bias drift of this sensor. This technique, which is based on orthocyclic winding, contains complex nonaxisymmetrical zones, for example layer transitions or crossovers. In this paper, a precise topological reconstruction of the sensing coil is proposed using X-ray computed tomography. Thanks to this reconstruction, the first layer role and its impact on the next layers are studied. Then, the quality of the winding is quantified using interest parameters to evaluate crossovers and layer transition fibers. Finally, winding defects, particularly the propagation of gaps from layer to layer that causes sinking fibers, are highlighted. |
