This study proposes a filtering tool based on the diffuse approximation, in order to reconstruct strain fields from full-field displacement measurements. The question of the filtering of the noise is adressed and an alternative approach based on space-time filtering is proposed. The methods are then applied to the detection of early damage detection on a tensile test on an interlock composite.
