Atomic scale displacements detected by optical image cross-correlation analysis and 3D printed marker arrays

Overview of the folder structure: -------------------------------- - These folders contain the actual optical images we took and that are the basis of our image cross-correlation (nomenclature is as in the paper): Sample1 - Copper Sample2 - Gold grains Sample3 - Array 1 Sample4 - Array 1 coated Sample5 - Array 2 coated Computer generated data each of these folders contains two subfolders 'drift' and 'step' containing the data referring to the drift measurement and the step-function measurement depicted in Fig.5 of the paper. The folder 'Comuter generated data' additionally contains a folder 'supplementary figureS1 data', which contains the data for said figure. The specific parameters are mentioned in the folder name (see numbers behind 'sig_x' and 'amplitude') - These folders contain the matlab scripts needed to perform the image cross-correlation and create the computer generated data. Matlab scripts Digital Image Correlation - These folders contain .stl files of the printed marker arrays Fabrication
