Abstract :
Full-fiber optical current sensors utilize the effects of magnetic-field imposed on the change of polarization azimuth of light in the fibers, it has a lot of advantages over conventional current sensors and have been studied extensively. To eliminate the vibration sensitivity, a light path of reflective fiber optic current sensor improved is proposed, which makes discharge of Sagnac effect with Sagnac effect itself and do not disturb Farady effect at all. And then, several factors cause the relative error in sensor of Y waveguide polarizer are analyzed with Jones matrix. The results provide a possible reference for further research in the FOCS techniques area.
