Abstract

We review basic metrological terms related to the use of measurement equipment for verification of numerical model calculations. We address three challenges that are faced when performing measurements in experimental mechanics with optical techniques: the calibration of a measuring instrument that (i) measures strain values, (ii) provides full-field data, and (iii) is dynamic.
