In this paper we are presenting a ΓΏltering scheme using Symlet wavelet to remove the speckle noise from the time-averaged digital speckle pattern interferometry fringes. To demonstrate the potential of Symlet wavelet ΓΏltering, experiments are conducted to remove the speckle noise from the fringes re
