摘要
A method and instrument for measuring, with a high spatial resolution, a magnetic or electric field that varies repeatedly at high speed. An electron beam is deflected by passage through a magnetic or electric field to be measured and is allowed to pass through a deflection electrode to thereby be deflected in a direction perpendicular to the magnetic or electric field to be measured. A track of the deflected electron beam is detected by a two-dimensional sensor, and a waveform or pattern is displayed wherein a time base and an axis of the magnetic field to be measured are orthogonal to each other.
