Abstract:
1. An optoelectronic system for sensing an electric field signal, comprising: An optically modulated scattering module to convert an electric field signal into a modulated scattering signal based on an optical modulation signal, wherein the optically modulated scattering module comprises at least one optically modulated scattering including: An optoelectronic sensing module to receive the modulated scattering signal; A detection circuit to detect the modulated scattering signal received by the optoelectronic sensing module based on an electric modulation signal; and A signal processing circuit electrically connected to the detection circuit and to calculate the amplitude and phase of the electric field signal, Wherein the optically modulated scattering module comprises a plurality of scattering antenna sets disposed on the substrate in an array manner, and each of the scattering antenna sets includes a first scattering antenna and a second scattering antenna perpendicular to the first scattering antenna.
