Figure 3From: Non-equidistant scanning approach for millimetre-sized SPM measurementsAdaptive measurement process illustration. The graph shows the convergence of the z value of a typical point on a flat sample area (point A) and close to a steep slope (point B) if the iterative refinement process is not stopped by the precision criterion. The precision criterion is used to stop refinements locally as shown in the inset.Back to article page
