Integral Paraphrase of Physical Parameters of Non-uniformly Induced Medium in Optical Current Transformer

: The three global physical quantities is presented to reveal optical sensing properties of a non-uniformly induced medium. The study found that, the sine function of average induction angle is the weighted integral of sine function of induction angle of optical path; the exponential function of average uneven angle is the weighted integral of exponential function of uneven angle of optical path; the global phase shift difference is the weighted integral of induced birefringence of optical path. The values verify that physical quantities have a specific but non-approximate integral relation with the corresponding physical quantity of optical path.
