Abstract

The present invention relates to an electrode antenna unified photoelectric integrated sensor used for making strong electric field measurement, belonging to the field of high-voltage measurement technology. It is characterized by that it adopts a wafer with electro-optic effect, on the wafer surface said invention adopts titanium metal diffusion process or proton exchange process to form optical waveguides whose two ends are made into the form of Y-shaped bifurcation and middles are mutually parallel, on two mutually-parallel optical waveguides three inverted U-shaped electrode antennas whose tops are respectively equipped with a projection are set, said three mutually-parallel inverted U-shaped electrode antennas are crossed over two mutually-parallel optical waveguides. The invented photoelectric integrated sensor can be used for measuring the information of amplitude, frequency and phase of strong electric field signal.

Description

technical field [0001] The invention relates to an electrode-antenna integrated photoelectric integrated sensor for strong electric field measurement, which is especially suitable for sensor isolation and strong electric field signal measurement under the condition of high electric field amplitude, and belongs to the technical field of high voltage measurement. Background technique [0002] In high voltage or electromagnetic pulse environments, very strong electric fields can be generated. The key component to measure it is the electric field sensor. The sensor must not only be able to withstand strong electric field environments, but also be able to measure strong electromagnetic fields with high amplitudes. [0003] In the field of traditional high-voltage measurement, sensors based on the principle of electromagnetic induction are generally used for electric field measurement. The strong electric field sensor based on the principle of electromagnetic induction has the f...
