  • Electromagnetic field sensing apparatus
    Patent number: 7209613
    Abstract: An electromagnetic field sensing apparatus includes an optical modulator, a miniature antenna for sensing the electromagnetic field, a light source, a first optical fiber, an optical detector and a second fiber. The optical modulator can vary the amplitude of a light beam propagating therethrough in response to an electric field intensity. The miniature antenna for sensing the electromagnetic field can sense both the electric field intensity and the magnetic field intensity of an electromagnetic field and apply an electric voltage to the optical modulator in response to the sensed electromagnetic field intensity. The light source is used to generate a light beam, the first optical fiber is used for transmitting the light beam to the modulator, and the second fiber is used for transmitting the light beam from the modulator to the optical detector.
