摘要：
The measurement of alternating current (AC) is realized by using fiber Bragg grating (FBG), giant magnetostriction material (GMM), and the technology of fiber coupler demodulation (fiber wavelength division multiplexing filter, FWDMF). The magnetostrictive effect of GMM, the theoretical analysis of the FBG current measurement and the interrogation technology of FWDMF are introduced as well. The sensing unit of AC current measurement is constructed with magnetostrictive material and FBG. The feasibility of AC current measurement by using this method is proved, when the AC exciting current is in the scope of 0 similar to 2A.
