Digital Image Correlation

ARAMIS

ARAMIS is a non-contact and material-independent measuring system based on digital image correlation. It offers a stable solution for full-field and point-based analyses of test objects of just a few millimeters up to structural components of several meters in size.

The system performs high-precision measurements with a 3D measurement resolution in the sub-micrometer range, regardless of the specimen’s geometry and temperature. There is no need for a time-consuming and expensive preparation. For statically or dynamically loaded specimens and components, ARAMIS provides accurate:

  • 3D coordinates
  • 3D displacements, velocities, accelerations
  • Surface strain
  • Evaluations of 6 degrees of freedom (6DoF)

What is DIC (Digital Image Correlation)?

Digital image correlation (DIC) is an optical non-contact method to measure 3D coordinates for the evaluation of 3D surfaces, 3D motion and deformation. Stochastic patterns and/or point markers are utilized to describe discrete image areas, which can be determined with subpixel accuracy by analyzing the image information.

With this principle, point-wise and full-field measuring results are created and used for a wide range of applications in materials research and component testing to determine the static and dynamic behavior of specimens, such as displacements and strain. Thus, DIC enables an analytical investigation of the complex behavior of any test object.
