Abstract
We measured microwave-power space distribution using an electric-field sensor utilizing the electro-optic effect. The sensor is a small optical interferometer on an electrooptic crystal with a dipole antenna. Since the sensor does not include electrical parts except for the dipole antenna, the sensing with less disturbance is possible. The sensing system is optical fiber connected system. So the system can be used in an electromagnetic wave shielded space such as in the underground space.
