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
