Abstract

Nonlinear transduction mechanism in electrostrictive and magnetostrictive materials is exploited to demonstrate multiplexed low frequency fiber optic electric and magnetic field sensors. The sensor utilizes a single interferometer and a single unmodulated laser while demonstrating extremely low cross-talk between the electric and magnetic channels. Low frequency electromagnetic signals from remotely located electric and magnetic dipoles are detected with the fiber optic sensor.
