OPTICAL CURRENT SENSING ELEMENT WITH POLARIZATION PRESERVING COATINGS FOR FARADAY CURRENT SENSOR
用于Faraday电流传感器的保偏膜光学电流传感元件

The design and the performance of a novel optically based Faraday current sensing element with polarization preserving totally reflecting single medium layer coatings for optical current sensing system at high voltages are reported.The sensitivity is improved by a factor of 86 7% experimentally comparing with the same head without the layers.Five of the advantages of employing this newly designed sensing element in optical current sensing system are introduced.
