Electric current may be measured very conveniently by utilising the Faraday magneto-optic effect in a monomode fibre looped around a conductor. Devices based on this idea presently suffer from a sensitivity to vibration. This paper explains the nature of the vibrational sensitivity, and proposes a number of techniques which could reduce it to acceptable levels.
