Optical full-ﬁeld measurement methods are increasingly used in the ﬁeld of experimental mechanics, and several techniques have been developped to make the most of the redundancy of the measured ﬁelds. However, the number of modelling parameters that can be retrieved is strongly connected to the noise level corrupting the measured ﬁelds. Focusing on the techniques based on the construction of a statically admissible ﬁeld from the experimental data, a two-scales approach is proposed. It relies on the fact that, using a ﬁnite-element description of the struture, the larger the number of degrees of freedom to be measured, the more degraded by noise. It is therefore proposed to use displacement ﬁelds measured at two diﬀerent scales. This paper describes the way the macro displacement ﬁelds basis is built.
