ABSTRACT:
An improved method and apparatus for measuring a target electric current utilizing a Faraday effect in which an optical medium is magnetically coupled with the target electric current and light is passed through the optical medium at an orientation for which the effects of birefringence on the optical medium can be disregarded in comparison with the Faraday effect, and the light departing from the optical medium is measured and analyzed in a manner permitting the target current to be accurately determined.
