Using laser marking to engrave optimal patterns for in‐plane displacement and strain measurement
Strain, 2021 The checkerboard constitutes the best pattern for in‐plane displacement and strain measurement because it maximizes image gradient. The use of laser marking to deposit such a pattern on flat surfaces is investigated in this paper.
