| Abstract: | The ring iron core with the air gap in the structure is introduced, and the photoelectromagnetic current sensor of Faraday Effect is designed with the new sensing element, The sensing element is a fine glass prism which has the high reflection coating at two ends. The beam propagated through the prism is reflected critically 20 times at the interface of glass and air. The new sensor has the higher sensitivity three times than the similar products. |
