叙述了一种采用电子学全息法分析三维物场的定量方法。它包括：１）三维物场全息图的数字记录，２）全息图面上复振幅分布的数字再现，３）利用空间频域衍射公式计算其它平面（平行于全息图面）上的复振幅分布。由此可以获得整个三维物场的信息。本文同时还给出了这一数字再现方法的空间分辨率。最后通过计算机模拟展示了一个理想三维物场的再现过程及再现结果
A quantitative method for analyzing three-dimensional object fields using electronic holography is described. It consists of: 1) digital recording of the hologram in a three-dimensional object field, 2) digital reproduction of the complex amplitude distribution on the hologram surface, 3) complex space amplitude distribution on other planes (parallel to the hologram surface) using the spatial frequency domain diffraction formula . This can get the information of the entire three-dimensional object field. This article also gives the spatial resolution of this digital reproduction method. Finally, computer simulation shows an ideal three-dimensional object field reproduction process and the reproduction results
