Abstract
In civil engineering, a significant part of the experimentation should be performed on real, full-scale structures, either in situ or in ad-hoc testing halls. Under these conditions, micro-deformation measurements using interferometric methods are certainly not an easy task and could even appear meaningless.
The general orientation of this paper is, however, to present recent improvements towards the possibility of using speckle interferometry for micro-displacement analyses of large surfaces outside the laboratory. Two main categories of arguments are considered. First, the results of an in-depth statistical analysis of speckle interferometry, showing in which way it is judicious to optimise the interferometric signals, are summarised. Then, the advantages of a dynamic phase-shifting technique, involving the recording of sequences of time-varying speckle interferograms, and the resources of wavelet analysis, are emphasised.
