Verfahren zur beruehrungslosen Anregung von Torsionsschwingungen in einem einseitig eingespannten Federbalken eines Rasterkraftmikroskops

WO2004102583 A UPAB: 20050112 NOVELTY - The method uses an acoustic coupling medium (7) between the sprung cantilever (3) and an underlying surface which is subjected to linearly polarized lateral oscillations, for excitation of free torsional oscillations in the sprung cantilever. The polarization axis of the lateral oscillations is perpendicular to the longitudinal direction of the sprung cantilever. USE - The method is used for exciting free torsional oscillations in a sprung cantilver of an atomic force microscope for elasticity measurements. ADVANTAGE - Method provides simple free torsional oscillation of sprung cantilever having a length of 6cm or less
