快速傅里叶变换迭代法在三维流场显示中的应用

Application of Fourier Quick Variation Repeat Method to 3-D Refraction Index Field Representation

本文在分析了快速傅里叶变换及有限观察角再现理论的基础上，使用快速傅里叶变换迭代法对三维流场中不含遮挡物的有限观察角进行了再现。

Based on analysis of the Fourier Quick Variation and the representation theory of the finite observation angle, this article illustrates a representation approach to the finite observation angle without blocking in the 3-D refraction index field by the Fourier Quick Variation Repeat Method.
