Abstract (en)

[origin: WO2004102583A1] The invention relates to a method for exciting free torsional oscillations in a sprung cantilever, which is fixed on one side and has a longitudinal extension, of an atomic force microscope (AFM). The invention is characterised in that the sprung cantilever, fixed on one side, is placed above a surface at a distance from the latter, an acoustic coupling medium being located between said surface and the sprung cantilever, that the surface is subjected to lateral oscillations that are polarised in a linear manner along an oscillation direction and that the polarisation axis defined by the oscillation direction runs perpendicular to the longitudinal extension of the sprung cantilever.
