Fiber-optic gyroscope for the suppression of a Faraday-effect-induced bias error

Aylin Yertutanol et al.

Summary: Interferometric fiber-optic gyroscopes (IFOGs) are widely used in military and industrial applications for their high sensitivity and stability. A new fiber coil design is proposed in this study to reduce magnetic field sensitivity without adding optical components or electronic algorithms to the IFOG system, resulting in a significant reduction in bias error. This design allows for the compensation of Faraday-effect-induced bias error by allowing two different polarizations to travel inside the fiber coil, reducing bias error by approximately 20 times in experimental results.
