Effects of Window Size on Accuracy and Spatial Resolution in Windowed Phase‐Shifting Digital Holographic Interferometry1

:  Phase‐shifting digital holographic interferometry is a new method to measure displacement distribution on the surface of an object. Usually holography has speckle noise, which leads to a large error in the analysis of displacement and strain distributions. We previously proposed windowed phase‐sh...
