ELECTRO-OPTIC VOLTAGE SENSOR |
摘要 |
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.
