This thesis demonstrates and investigates novel dual-polarization interferometric fiber-optic gyroscope (IFOG) configurations, which utilize optical compensation between two orthogonal polarizations to suppress errors caused by polarization nonreciprocity. Further, it provides a scheme for dual-polarization two-port IFOGs and details their unique benefits.

Dual-polarization IFOGs break through the restriction of the "minimal scheme," which conventional IFOGs are based on. These innovative new IFOGs have unique properties: They require no polarizer and have two ports available for signal detection. As such, they open new avenues for IFOGs to achieve lower costs and higher sensitivity.

Nominated by Peking University as an outstanding Ph.D. thesis Describes the optical compensation mechanism for polarization error suppression in interferometric fiber-optic gyroscopes (IFOGs) Provides a scheme for dual-polarization two-port IFOGs and details its unique benefits Breaks though the restrictions of the conventional minimal scheme for IFOGs Opens new avenues for IFOGs to achieve lower costs and higher sensitivity Includes supplementary material: sn.pub/extras

The author has been studied fiber-optical sensors since 2008. In recent years, his researches mainly focus on the interferometric fiber-optic gyroscope (IFOG). His research achievements include novel structures and optimized signal processing methods for IFOGs. Especially, he discovers the optical compensation mechanism for IFOGs, together with his research group. With this mechanism, polarization errors can be efficiently suppressed within dual-polarization IFOGs.
