Fiber Optic Electric Field Sensor Investigations. II.
Abstract
In June 1981 the Office of Naval Research contracted with Tracor, Inc. to experimentally investigate the potential of interfacing piezoelectric polymers and single mode fibers for the development of an optical fiber electric field sensor. The continuation and conclusion of that effort is reported herein. Experiments were performed whereby a single mode fiber was embedded in a piezoelectrically active vinylidene fluoride-tetrafluoroethylene copolymer film. Application of an external electric field to the fiber copolymer composite induces strains in the polymer film that are transferred to the core of the optical fiber. The resultant phase shift in the propagating light is detected with a Mach-Zehnder interferometer and correlated to the amplitude of the applied electric field.
