A new technique for three-dimensional (3D) electric-field (e-field) vector measurement is presented. Three laser beams with different propagation paths in an electro-optic (EO) crystal were used to resolve 3D components of e-field vectors. We adopted a special geometric shape of bismuth silicon oxide EO crystal so that the three beams would propagate within it. A sensitivity of 0.6 V/cm square root Hz was achieved. A commercial Ansoft Maxwell 3D field simulator was also used to verify our measurements.
本文提出了一种用于三维（3D）电场（e-field）矢量测量的新技术。利用在电光（EO）晶体中具有不同传播路径的三束激光来解析电场矢量的三维分量。我们采用了特殊几何形状的铋硅氧化物电光晶体，以便三束激光能在其中传播。实现了0.6 V/cm√Hz的灵敏度。还使用了商业Ansoft Maxwell 3D场模拟器来验证我们的测量结果。
