Electric field sensor capable of reliably measuring an electric field intensity of a signal |
摘要 |
An electric field sensor includes an electric field sensor head (13) for varying an intensity of a propagating light beam from a light source (19) in response to an electric field intensity of an input signal received by a reception antenna (11). A photo-electric converter (21) converts the propagating light beam into an output signal. A correcting device (27) compares the output signal with a reference signal to produce and supply a control signal to the photo-electric converter.
