An electro-optic voltage sensor system includes a sensor (40) disposed in an E- field, a transmitter (34) for producing the electro-magnetic beam, detectors (162, 164) for converting the two beams into electrical signals and a signal processor (174) for determining the voltage. The sensor (40) receives a source beam (38) and includes a polarization beam displacer (80) for separating the source light beam (38) into two beams with orthogonal linear polarizations, a wave plate (104) for rotating the linear polarization to rotated polarization, a transducer (114) utilizing pockels electro-optic effect for inducing a differential phase shift on the major and minor axes of the rotated polarization in response to the E-field, a prism (130) for redirecting the beam back through the transducer (114) and also converts the rotated polarization to circular or elliptical polarization.

Un système de capteur de tension électro-optique comprend un capteur (40) placé dans un champ électrique (champ E), un émetteur (34) qui produit le faisceau électromagnétique, des détecteurs (162, 164) qui convertissent les deux faisceaux en signaux électriques et un processeur (174) de signal qui détermine la tension. Le capteur (40) reçoit un faisceau source (38) et comprend un dispositif de déplacement (80) de la polarisation du faisceau qui sépare le faisceau (38) de lumière source en deux faisceaux ayant des polarisations orthogonales linéaires, une plaque mobile (104) qui fait tourner la polarisation linéaire en polarisation orientée, un transducteur (114) qui utilise l'effet électro-optique de Pockels pour induire un déphasage différentiel sur les grands et les petits axes de la polarisation orientée en réponse au champ E, un prisme (130) qui renvoie le faisceau par le transducteur (114) et qui convertit également la polarisation orientée en polarisation circulaire ou elliptique.
