Abstract
A device for measuring electric fields mainly comprises a laser and a probe provided with a centrosymmetric polymer sheet permitting the generation, under the action of the field, of the second harmonic of the emitted wavelength. Optical fibers carry the incident and reflected waves of the laser to the probe and then to an optical measuring cascade. This device is of particular interest for measuring the electric fields between high voltage coaxial cables.
