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.

• These folders contain .stl files of the printed marker arrays
