摘要
This paper present the design of a current sensor based on Faraday Effect using optical fibers devices and a polarizing beam splitter (PBS). Two different schematics are to be taken into account, for high currents and for smaller ones. A single polarized laser signal is sent to the PBS prism and two angular components are separated. From here, these optical signals are processed using some interfaces, a NI-DAQ acquisition board and a Lab VIEW interface. After calculations, the unknown current is obtained function of the reflexion angle between the two light components.
