Digital Image Correlation

Full-Field Insight Into How Structures Really Behave

Every structure deforms under load. The question is whether you see it fully or rely on a handful of point measurements and hope nothing critical falls between the gaps.

26+ Years of Expertise

The most experienced DIC team in North America

Trilion has specialized in DIC for over 26 years, making us one of the most experienced teams in North America for optical strain measurement. As a ZEISS Certified Partner, we deploy the ARAMIS family of systems, purpose-built for everything from sub-millimeter coupon tests to multi-meter structural assemblies.

Our engineers do not just sell hardware; they work alongside your team to set up, validate, and interpret results so you get defensible data, not just pretty color maps.

Sensor Coverage

Not a strain gauge. Optical strain

Strain gauges and extensometers measure at discrete points. If a crack initiates, a hotspot develops, or load paths shift between those points, you will not see it until failure. ARAMIS Optical Strain captures the full displacement and strain field across the entire specimen or component surface, revealing unexpected concentrations, asymmetries, and failure precursors that point sensors structurally cannot detect.

FEA Validation

Correlating simulation with physical testing

FEA models predict behavior, but validating those predictions requires measurement data at matching resolution. Point sensors leave large areas of a model unverified. ARAMIS Optical Strain delivers dense, full-field strain and displacement that maps directly onto FE meshes, enabling quantitative comparison at thousands of points simultaneously.

Scale & Speed

Testing across scales and speeds

Real engineering programs span coupon-level material characterization, component fatigue, and full-scale structural proof tests, sometimes at high strain rates. ARAMIS Optical Strain scales from a single-camera 2D setup on a tensile machine to a multi-camera 3D array covering meters of surface area, and supports high-speed acquisition for dynamic and impact events. One ecosystem, consistent data formats, one software environment from coupon to structure.
