ABSTRACT:
A device for measuring an electric field comprises three optical fiber sensors, which each have a piezoelectric sensor element, as well as an interferometer for generating a sensor signal. The optical fiber sensors have piezoelectric sensor elements that exclusively detect with the aid of the inverse piezoelectric effect a predetermined directional component, assigned in each case, of the electric field. The directional components of the different sensor elements are each aligned perpendicular to one another. An evaluation circuit determines the absolute value and direction of the electric field from the sensor signals generated.
The sensor elements are preferably formed by a single piezoelectric body, on whose faces the sensor fibers are fixed.
