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.
