title = "Optical voltage sensor using single Fresnel rhomb Bi4Ge 3O12 crystal",
abstract = "A novel optical voltage sensor is proposed and experimentally demonstrated by use of single Fresnel rhomb bismuth germanate crystal. Different from previous polarimetric voltage sensors, the proposed voltage sensor can provide the π/2 optical bias by two times of total internal reflection of light wave in the crystal, thus any additional quarter wave plate is not necessary. In principle, the influences of measurand voltage and temperature on the π/2 optical bias are neglectable. The 50Hz ac voltage in the range of 2∼2000V is measured with good linearity.",
