Study on Polarization Errors of Re-entrant Fiber-Optic Current Sensor
摘要

Abstract
To improve the performance of fiber-optic current sensor (FOCS), a re-entrant fiber-optic current sensor was presented and with Jones matrix, its polarization error was studied. By establishing the Jones matrix expression of the main optical devices, an interference expression of re-entrant optical fiber current sensor was introduced and the influence of imperfection of optical devices on the measurement accuracy was analyzed.
