Abstract
A fiber-optic interferometric method for remote voltage measurement with simultaneous temperature measurement is presented. A PMN electrostrictive transducer is employed as a voltage-to-displacement converter. The displacement is then interferometrically measured by the passive demodulation technique based on a 3 × 3 fiber-optic coupler. The third 3 × 3 coupler's port and the same low coherence light source (LCS) are used for the interferometric temperature measurement, necessary for the correction of the electrostrictive coefficient values.
