Three-Dimensional Displacement Analysis by Windowed Phase-Shifting Digital Holographic Interferometry
Digital holography is useful to reconstruct three-dimensional shapes of objects. The reconstruction process of the objects is fast and accurate because the reconstruction is performed by computer calculation without developing photographic plate. Phase-shifting digital holographic interferometry is possible to measure shape and displacement of objects quantitatively. The authors developed windowed phase-shifting digital holographic interferometry (WPSDHI) which provides very accurate results by decreasing the effect of speckle noise.
