摘要: 
相位展開技術常會因雜訊和待測物原始形貌的不連續所造成的剪切線等因素而造成展開結果錯誤。對於雜訊的問題,經過多年的發展已有相當不錯的克服能力。在本篇論文中,主要是針對包裏相位圖中剪切線的搜尋和定位來做研究,以門檻值調整的方式來做搜尋和定位剪切線的動作。再提出另一種結合不連續點和非封閉跳躍線修補的方式,來對含雜訊的包裏相位圖做搜尋和定位剪切線的動作。

Phase unwrapping often results in a false unwrapped phase map because of noise or shear line of testing sample caused by its discontinuity of original form. As to noise, there have been many effective methods to get over the problem. The paper mainly focuses on looking for and locating the shear line of phase map by controlling the threshold value; and further, it is expected to bring up another method to look for and locate the shear line of phase map with noise by combining the discontinuous points and repaired unclosed jump line.
