Imperfection errors in glass block faraday effect current sensor

Abstract

Theoretical analysis of measurement errors caused by the imperfection of the sensing optical loop in a glass block Faraday effect current sensor has been presented. The experimental results with the fabricated sensor which was designed to achieve a closed homogeneous and isotropic optical path show the importance of the perfectly isotropic and closed loop, in accordance with the theoretical consideration.
