互易性光学量对FMOCT输出光偏振态的联合影响

A project of Faraday mirror-typed optical current transformer which is used in super-current measurement is proposed.Joint effects of reciprocal optical parameters upon the polarization state of output light of Faraday mirror-typed optical current transformer are analyzed by Jones Matrix.The results are simulated by computer.Elliptical degeneration of output polarization light is quantitatively analyzed by means of conception of the elliptical ratio.The relation between elliptical ratio of output light and reciprocal optical parameters is calculated.Compared with the optical current transformer with single layer polarization maintaining in the elliptical degeneration of output polarization light,the result shows that output light of Faraday mirror-typed optical current transformer is also maintain the polarization state under the condition of joint effects of reciprocal optical parameters.It will improve the influence of reciprocal optical parameters upon system stability by temperature and might have certain reference signification on the investigation of the practical optical current transformer.
