Dantec Dynamics specializes in the development, manufacture, and application support of measurement systems that acquire and analyze data of physical properties in fluids and solid structures. They deliver turnkey and customized solutions built on high-end laser optics, imaging, and sensor technologies. The product range we offer includes laser shearography and solidworks digital image correlation.
Laser Shearography is an optical, Non-Destructive Testing (NDT), surface measurement technique that works on the principle of laser-speckle shearing interferometry. Through the application of a load or excitation to an object‘s surface, a shearography sensor can observe surface bending in the form of an out-of-plane strain field. The measurement attained is imaged as a phase map that presents the relative difference in the two (reference/deformed) states as fringes. Local weaknesses in the structure, caused by discontinuities, are indicated as isolated fringes. Since the sensor is sensitive to laser light interference, it can detect bending within the sub-micrometer range.
Digital Image Correlation (DIC) is a 3D full-field, non-contact optical technique to measure contour, deformation, vibration and strain on almost any material. The technique can be used with many tests including tensile, torsion, bending and combined loading for both static and dynamic applications.
The DIC method can be applied from very small (micro) to large testing areas – and the results are readily comparable with FEA results or strain gauges.
