Polarization-maintaining Optical Fibre Coil

Fiber optic gyroscope (FOG) is an all-solid-state gyroscope which uses Sagnac effect to measure the rotating angular velocity. It has the characteristics of simple structure and wide dynamic range, and has become one of the main instruments in the field of inertial measurement and guidance technology. The core sensing element of FOG is polarization maintaining fiber coil, which mainly includes polarization maintaining fiber and curing adhesive. YOFC's polarization-maintaining fiber coil selects polarization-maintaining fiber with excellent performance and special curing adhesive, adopts multi-pole (monopole, quadrupole, octupole, and hexapole) symmetric winding method to form an all-solid fiber coil., which has the characteristics of high symmetry, high extinction ratio, low loss, etc.
