Multicore fiber optic gyro
Disclosed are systems and methods that utilize multicore optical fibers for gyro coil winding. Particularly, the use of multicore fiber enables inherent thermal stability without the need for complex, tedious, and costly winding patterns. Enabling the use of level winding techniques eliminates the need for complex quadrupole winding patterns. This simplicity lends itself to advancements towards full automation of winding coils for multicore fibers, without sacrificing performance. This, in turn increases the production rate and overcomes current barriers to fiber optic gyroscope (FOG) market expansion. In accordance with the embodiments, multicore fiber can be utilized in various gyro coil winding techniques, including: level winding; Interrupted Level Wind (ILW); and Dual Axis Symmetric (DAS) winding. Furthermore, each of the multicore fiber gyro coil winding patterns can incorporate a multicore shuffle bridge. The multicore shuffle bridge is designed to provide multiple features, such as facilitating the rotation of mating cores.
