2D Digital Image Correlation: Simply See More
2D digital image correlation visualizes deformations and strain over the entire visible specimen surface. The non-contact videoXtens extensometer records image series during the test, compares image by image, and calculates the displacement in a pre-defined facet field, where each facet includes a specified number of camera pixels. This data is used to create two-dimensional color strain maps, which allow you to analyze the specimen behavior at a glance.

Resolution specifications for virtual strain gauges with an edge length of 5x5 mm are dependent on the videoXtens system version: | ||
videoXtens 1-120 | 90 | µStrain1 |
videoXtens 1-270 | 150 | µStrain |
videoXtens 3-300 | 90 | µStrain |
videoXtens 2-120 HP | 25 | µStrain |
videoXtens biax 2-150 HP | 20 | µStrain |
Minimum version | testXpert III V1.61 |
The accuracy and resolution of the virtual gauge length corresponds with the videoXtens system used, i.e. videoXtens biax 2-150 HP: 0.15 µm and accuracy class 0.5 (ISO 9513)
- Explanation of the resolution specification: 100 µStrain correspond to 0.01% extension. Based on a gauge length of 5 mm, 100 µStrain correspond to a resolution of 0.5 µm.
