采用数字方法重构电子全息图，分别研究了荷电乳剂小球（０３１μｍ）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．
The electronic hologram was reconstructed by digital method. The micro-electric field distribution of charged emulsion beads (031μm) and the fine structure of magnetic field lines in ferromagnetic materials were studied respectively. The use of noise reduction and phase difference amplification technology to improve the reproducibility of resolution, and obtained some new results.
