A Fast Spatial Phase Unwrapping AlgorithmWith Suppressing Pull-Line Error as Far as Possible
ZHANG Ying, and CAO Yi-ping
Traditional line scanning spatial phase unwrapping algorithms can achieve rapid phase unwrapping,however,it is susceptible to pull-line error propagation caused by factors such as noise and defocusing,which can lead to reconstruction errors or even failure. In light of these challenges,this paper proposes a spatial pha
