Abstract

This paper presents a highly sensitive method of measuring mechanical strains. We combined the existing laser speckles technique and the new data-processing approach based on the wavelets. We have applied the directional continuous wavelet transform, which yields decompositions of image either in terms of dilation and rotation or time and rotation. In our study these properties of the wavelet transform have been used for evaluation of the spectral characteristics of speckle images and to track the dynamics of speckle motions.
