Indirect identification and compensation of lateral scanner resonances in atomic force microscopes

Georg Fantner

Improving the imaging speed of atomic force microscopy (AFM) requires accurate nanopositioning at high speeds. However, high speed operation excites resonances in the AFM's mechanical scanner that can distort the image, and therefore typical users of comme ...
