ABSTRACT:
A sensor utilizing a single electro-optic crystal for simultaneously measuring an electric field in three directions. By providing three light beams aligned along specific crystallographic directions and having specific polarizations, the crystal can simultaneously sense the electric field in three orthogonal directions. The crystal preferably has cubic symmetry and belongs to one of the point groups 43m or 23, such as crystals of bismuth silicon oxide or bismuth germanium oxide.
