[摘要]:Based on an isotropic electro-optic crystal, a two-port pigtailed electro-optic sensor has been built. The probe allows to measure two orthogonal components of the ambient electric field. The sensor intrinsically presents a temperature-dependent free response. The two measured electric field components are orthogonal to the sensor revolution axis, leading to a transverse electro-optic probe. Magnitude and orientation of the electric field are measured simultaneously with an accuracy of 0.5 dB and 2 degrees, respectively. The rejection of orthogonal components to the electric field vector reaches 30 dB. (C) 2011 American Institute of Physics. [doi:10.1063/1.3646103]
