A new digital speckle pattern interferometry, called volume-grating phase-shifting digital speckle pattern interferometry, is discussed in this paper. The out-of-plane displacement ΓΏeld of a bent plate can be quantitatively measured using volume-grating phase-shifting digital speckle pattern interfe
Several different gratings utilizing phase-shifts in their designs are fabricated and characterised: a uniform grating with a single phase shift in the centre, a sinc-profile grating (with intrinsic phase shifts at the zeros), and a stretched cosine apodised grating with multiple and arbitrary phase
