Abstract
An E-O probe for a two-dimentional voltage detecting apparatus using a fiber optic plate is provided. The fiber optic plate has a bottom face facing a measured object and a bundle of a plurality of cores separated from one another by cladding electro-optic material is attached to an end of each core at said bottom face side. A reflecting surface is provided on the bottom face side of the fiber optic plate for reflecting light back toward the side of the fiber optic plate opposite said bottom face. The refractive index of said electro-optic material varies in response to the intensity of an electric field applied to the electro-optic material. A two-dimentional voltage detecting apparatus using the E-O probe is further provided which has a high spatial resolution.
