The laboratory facilities (more than 1200 sensors, calibration devices and loading systems) allow for static and dynamic testing on elements ranging in size from millimeters to hundreds of meters, as well as acoustic tests on components and assemblies. Vision based measuring devices allow the 3D motion estimation and the reconstruction of shape and strain conditions. Customized measurement systems can be developed according to the customers’ requests.
