This paper describes interference microscopy using a liquid-crystal panel as a rewritable medium. This system makes it possible to observe the dynamic behavior of a magnetic field. Experimental results obtained while observing dynamic domain-wall motion in a thin permalloy film are shown.
Key words : electron holography, video-rate electron-holographic interference microscopy, liquid-crystal panel, dynamic observation
