- Polarization Maintaining PM Fiber Coil for Gyroscope, FOG, Fiber Optic Gyroscope

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. CSRayzer'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

Features:
Custom winding paterns
Coil winding service for wide range of sizes and shapes
Freestanding available
PM or SM fibers

A key element in a fiber optic gyro is the fiber coil. Its quality and consistent performance determine the overall accuracy of the fiber optic gyroscope. Our proprietary winding process, adhesive, and patented instrumentation are used to assure superior specifications. The resulting fiber optic gyros therefore have excellent scale factors and bias stability over their full operation temperature range (0.5 deg /h ~ 0.005 deg/h ).

Just tell us the ID, OD, H, and length of the coil & we will do the rest.
