A method for correcting non-linear drift distortions in all three coordinate axes of atomic force microscope (AFM) images is presented. The method involves two measurements of the sample with two orthogonal fast scan axes, dividing the AFM images into segments, determining the shifts of the surface features, and calculating the drift. This method allows for correction of nonlinear drift and can be applied to existing images by measuring the sample again.
A method to correct non-linear drift distortions in all three coordinate axes of atomic force microscope (AFM) images is presented. The method uses two measurements of the sample with two fast scan axes orthogonal to each other. Both AFM images are divided into segments and the shifts of the surface features of the segments of both images are determined. From these shifts subsequently the drift of both measurements is calculated. Depending on the segments used, significant non-linearities of the drift can be corrected. The two required measurements for this method do not have to be carried out in direct succession. With this method it is therefore possible to correct drift in an existing AFM image by measuring the sample again later. Although the method has been developed for AFM, it can also be used for other scanning probe microscopes.
