| 摘 要： | 衍射层析成像可划分为两步,即由散射数据确定目标空间谱,再由目标空间谱重建目标特性。本文通过计算机模拟讨论由Fourier 衍射定理所重建的目标空间谱,及其对成像的影响。

| Abstract: | Diffraction tomographic imaging is,in fact,a two-step schemes.First,onedetermines the spatial spectrum of object from its scattered fields.Then the target charac-teristics is reconstructed from the spatial spectrum.We discuss in this paper the affect ofthe spatial spectrum reconstruction on the image quality. |
