PM Fiber Coil FOG Components 135μm/100μm Diameter with 0.003°/h Precision for Compact Gyros
LIOCREBIF's fiber coils serve as the core component of fiber optic gyroscopes, featuring high-performance freestanding construction. These coils are wound using hexadecapole, octupole, or quadrupole symmetrical methods to minimize Shupe error during temperature fluctuations. The freestanding design eliminates spool framework strain effects, while the compact 135μm or 100μm diameter PM fiber enables significantly reduced coil dimensions for space-constrained gyro applications.
