Zb. Wang et al., A novel method for simultaneous measurement of current and voltage using one low-birefringence fiber, OPT LASER T, 30(5), 1998, pp. 257-262
A novel method for simultaneous measurement of current and voltage employin
g a single monomode low-birefringence (Lo-Bi) fiber is described. This uses
the Faraday effect for detection of current and the Kerr effect for detect
ion of voltage. The waveform of the output light intensity due to the Kerr
effect has been detected and the Kerr constant was measured as 5.4 x 10(-16
) m/V-2 at 25 degrees C. Theoretical analysis shows that the current compon
ent can be measured free from the influence of the voltage component and th
e two components can be easily separated. (C) 1998 Published by Elsevier Sc
