Abstract

We report a novel, to our knowledge, current sensor based on a fiber Bragg grating (FBG). Using a cantilever beam and a linear magnetic actuator, the change of current is transferred to the Bragg wavelength shift of the FBG with good linearity and repeatability. The current sensor thus gains the merits of FBG sensors, and thus is immune to light intensity fluctuation, multiplexing capability, etc., and can be adopted for real industrial monitoring.
