Paper Abstract

A technique for the measurement of electric current using highly-birefingent optical-fibre is reported. The technique involves a resonant coupling between the fibre beat length and the period of a spatially-varying magnetic field. The resonant nature of the coupling makes the sensor less susceptible to environmental perturbations, than conventional lowbirefringence optical-fibre current sensors. The response of the coupling to distributed loads, and temperature compensation of the coupling are reported.
