摘要
在位相展开的过程中 ,对于具有病态特性的截断位相 ,如何有效处理极点和截断是至关重要的。本文基于位相展开过程中出现的问题提出了方法 :将相位图中的极点划分为 3类 ,奇异极点、常规极点和虚拟极点 ;就直线截断和曲线截断对于位相展开误差进行了定性分析。同时 。
In phase unwrapping,how to control residuals and cut lines is the key to unwrap ill state wrapped phase map successfully.In this paper,we provide new concepts in phase unwrapping field.Firstly,we have classified residuals in three types,singular residuals,normal residuals and virtual residuals.And secondly,we have analyzed some differences between cut line and curved line.And,we propose an enhanced Goldstein algorithm to connect the different residuals.
