ABSTRACT:
The optical electric current sensor is composed of a birefringent light guide (2) coiled around an electric current conductor (1) and is characterized by a spatial modulation of the magnetic field or of the birefringence of the light guide, along the light guide, at a spatial period equal to a whole number of times the beat length of the guide.
