Description:
The laboratory facilities (more than 1200 sensors, calibration and loading devices) allow performing static and dynamic tests on elements with scales ranging 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. Fit for purpose measurement systems can be developed according to the customers’ requests.
