| Abstract: | Tbedesign and the performance of an optically based Faraday current sensing systememploying a novel sensing element,using the so-called“complementary reflections”scheme,isreported.This new design not only increases the overall sensitivity of the device by a factor of three,but also makes it easy to align the current measuring element in the system,With the use of this newoptical element,a sensitivity of 6.57×10-5rad/A and a minimum detectable current of 11.3mA/√Hz have been achieved. |
