Fig. 2From: Measuring acceleration fields via regularized digital image correlationStandard displacement (a) and acceleration (b) uncertainties as functions of the static (\(\ell _S\)) and dynamic (\(\ell _D\)) regularization lengths. Comparison with instantaneous and spatiotemporal analyses. The physical size of one pixel is 200 \(\upmu \)m. The same type of compromise between measurement uncertainty and spatial resolution is found in comparison with instantaneous and spatiotemporal DICBack to article page
