A Comparative Guide to Optical Strain Measurement Methods: Local DIC vs. Global DIC – Which Method Is Best Suited for Your Application?

A Comparative Guide to Optical Strain Measurement Methods: Local DIC vs. Global DIC – Which Method Is Best Suited for Your Application?

2026-03-12

The key to choosing the right method lies not in algorithmic performance, but in the intended use of the data. For testing laboratories that need to feed measurement results into simulation models, global DIC based on the finite element method is the optimal solution. It generates data ready for immediate use—no post‑processing required, no interpolation bias, and no spatial transformation needed.
