A non-intrusive Moire interferometry system has been designed to acquire the instantaneous deformation of models during wind tunnel testing. The resulting interferograms are evaluated without manual intervention using a technique based on the Fourier Transform. The system has been installed in the cryogenic European Transonic Wind Tunnel (ETW). The deformation of a model wing (generic model of a transport aircraft with a full span of 1.60m) has been measured. In a second experiment, the bending angle of a flap of a hypersonic vehicle was measured in order to determine the hinge moment due to aerodynamic loads. The experiment was carried out in the Transonic Wind Tunnel Göttingen (TWG)
