Fiber sensor for simultaneous measurement of current and voltage by single Lo-Bi fiber

A sensor using a single monomode low-birefringence (Lo-Bi) fiber for simultaneous measurement of current and voltage has been designed, which uses Faraday effect for detection of current and Kerr effect for detection of voltage. Theoretical analysis proved the current component can be measured free from the influence of the voltage component, and the two components can be easily separated. Experimental results demonstrate the feasibility of the Kerr effect of the Lo-Bi fiber for sensing voltage, which is the main point in this proposal.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
