Abstract
In this paper we are presenting a filtering scheme using Symlet wavelet to remove the speckle noise from the time-averaged digital speckle pattern int erferometry fringes. To demonstrate the potential of Symlet wavelet filteri ng, experiments are conducted to remove the speckle noise from the fringes recorded for the surface of computer hard disk. Experimental results demons trate that this filtering removes the speckle noise to the large extent. (C ) 2001 Elsevier Science Ltd. All rights reserved.
