Next Generation 3D Optical Measurements for Manufacturing 2005-01-0490
Materials qualification, forming analysis, component and structural testing, advanced video metrology systems utilizing photogrammetry and image correlation provide robust full-field measurement capabilities for broad ranges of measurement applications. These advanced techniques of 3D image correlation (ARAMIS) for 3D deformation and strain measurement, photogrammetry (ARGUS) for automated forming analysis for manufactured parts and dynamic photogrammetry (PONTOS), are substantially more robust and provide a greater dynamic range than other technologies, and are simpler to use and less expensive to implement.
The technologies are inherently three-dimensional, measuring total deformation of complex objects and their shape, rather than just relative deformation. The technology also has a much higher dynamic range of deformation measurement, which is particularly critical during dynamic deformation analysis such as during systems analysis, plastic deformation and defect propagation.
