ARAMIS Digital Image Correlation System Software Interface


The ARAMIS digital image correlation system is an advanced 3D measurement tool for better understanding material and component behavior.

ARAMIS is a non-contact and material independent measuring system providing high resolution images, and highly accurate information about a component’s 3D shape, as well as strain and deformation response for a test article subject to a load or force.

The Digital Image Correlation system is an optical replacement for strain gauges, extensometers, accelerometers, LVDTS, laser trackers, laser scanners, scanning laser vibrometers, and other deformation tools.

An operator could expect all of these capabilities in one complete package.

This advanced Digital Image Correlation system documents, calculates, and analyzes the deformation in 3 dimensions and easily integrates into existing processes and testing environments. ARAMIS produces experimental results that directly compare with finite element analysis.

Features and Benefits

  • Digitally replaces analog instrumentation including strain gauges, extensometers, LVDT’s accelerometers, surface profilometers.
  • ARAMIS Digital Image Correlation system is a non-contact method of measurement; strain can be measured for materials in circumstances where extensometers may slip on the specimen during testing, may be cumbersome to use, or in cases where strain gauges cannot be applied.
  • Digital Image Correlation systems measure the complex 3D shape and shape change over time (deformation). Rather than the single point output of a strain gauge, the ARAMIS system provides a full-field 3D strain distribution.
  • A unique understanding of materials response can be obtained from visualizing how the distribution of strain changes across the field of view as load (or temperature, etc.) is applied. As a result, strain and displacement in the x, y, and z planes can be obtained at any point on the surface, at any time during the test.
  • Graphical representation of the results provides an optimum understanding of material response.


  • Strain computations for materials and complex components.
  • 3D Shape capture and comparison to CAD.
  • Characterization of creep and aging processes for long term health monitoring.
  • Examination of non-linear behavior.
