Paper Abstract

By means of the classical theories of electromagnetism, the authors discuss the Faraday effect in several kinds of ordinary media. According to the results of the theoretical analysis, an optimal magneto-optic material, SF8 dense flint glass, was chosen to make the sensing head of an optical fiber magneto-optic current sensor (OFMCS). A novel sensing head was designed based on the theories of physical optics, in which the linear polarized light is propagated without the polarization fading effect. Consequently, a high measurement accuracy and long- term stability is achieved.
