Fiber-optic current sensor

Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor''s current-generated magnetic flux, which reflects off a mirror. The light experiences a reciprocal phase shift as the refractive index, and effective path length, is modulated by the presence of a magnetic field, which optically induces circular birefringence. The interference pattern relative to a reference waveform is an optical intensity value corresponding to the
