Digital Image Correlation System

Digital image correlation (DIC) is a non-contact full-field optical strain measurement technique used in conjunction with various mechanical testing techniques. Samples are speckled and a series of images is captured at a fixed frequency using high-resolution cameras synchronized with the load frame. The VIC 3D and ARAMIS software packages are used to analyze the images and compute strain measurements.


  • Macroscopic and microscopic lenses for large and small sample areas, respectively
  • Image resolution options between 0.5 and 10 megapixels
  • Measured strain accurate to better than 100 microstrain
