Abstract

The linear birefringence exhibited by the wound fiber in a Faraday rotation current sensor is shown to be responsible for a significant dependence of the output signal on the location of the conductor within the fiber loop, and for non-zero outputs for conductors outside the loop. Numerical calculations show a signal variation of up to approximately equals 10% as the conductor is moved around the circumference of the loop.
