Ideal Phase map Extraction Method and Filtering of Electronic Speckle Pattern Interferometry
초록
Deformation phase can be obtained by using Least-Square Fitting. In extraction of phase values, Least-Square Fitting is superior to usual method like as 2, 3, 4-Bucket Algorithm. That can extract almost noise-free phase and retain 2
