  • Abstract
    A multimode fibre has been used to detect electrical currents. The optical fibre which serves as the sensor is coated with a thick Al metal jacket. Electromotive forces on a wire in a magnetic field are used to induce differential phase shifts between the fibre modes. Good linearity has been observed in the 5 to 2000 mA current range.
