ABSTRACT:
An electrooptic probe for measuring voltage of an object without contact with the object. The electrooptic probe according to the present invention includes an electro-optic material having a refractive index to light that varies in accordance with an electric field, a conductive reflecting film for reflecting an incident beam transmitted through the electro-optic material, fixed to an end face of the electro-optic material facing the object to be measured, a transparent electrode fixed on the other end face of the electro-optic material, and a high permittivity film fixed on an end face of the reflecting film facing the object to be measured.
