摘要 采用数字方法重构电子全息图,分别研究了荷电乳剂小球(031μm)的微电场分布及强磁材料中磁畴的磁力线分布精细结构.利用噪声消除及位相差放大技术提高了重现分辨率,并获得了一些新结果. AbstractElectric microfields inside or outside charged latex particles(0.31μm) and fine structure of magnetic domains in a permalloy film,are investigated by digital reconstruction from electron holograms.Resolution is improved by means of noise filtering and phase difference amplification.Some new results are reported.
