3D Visual Image Correlation
Non-contact strain measurement Digital Image Correlation (DIC) technology provides three-dimensional measurements of shape, global displacement and relative displacement (strain) on the surface an object using an optical method. Generally, DIC systems involve two or more imaging sensors (cameras) to provide sufficient information to for the software to triangulate and track objects in three dimensions. With the help of a randomized speckle pattern applied to the object’s surface, DIC systems can resolve displacements into continuous stress and strain measurements within the area of focus. Some of the main advantages of DIC systems include: Suitable for small- and large-scale objects Capable [...]
