Research on depolarized technology of interferometric all-fiber optic depolarized gyroscope

This paper discussed the evolution of polarization states in optical fibers using the knowledge of polarized optics, based on the analysis of principle of interferometric all-fiber optic gyroscope. This paper also focused on the theoretical deduction and experimental analysis of the depolarized theory, the depolarized process, the design of depolarizer, the realization of depolarized technology and the relation between the depolarizer precision and the depolarized gyroscopes performances. Based on it, this paper pointed out the essence of the depolarization and validate its correctness.
