Patent ID: 7958563

Claim:
A method of using an atomic force microscope by means of amplitude modulation, the method comprising the steps of: exciting at least one natural lower vibration mode and one natural higher vibration mode of a microlever of said atomic force microscope, analysing at least one of a variation of one variable of a first output signal that is representative of a response of said microlever to said excitation of said lower vibration mode, with respect to a variation of at least one parameter which is influenced by one variable of a second output signal that is representative of a response of said microlever to said excitation of said higher vibration mode, and a variation of one variable of the second output signal that is representative of a response of said microlever to said excitation of said higher vibration mode, with respect to a variation of at least one parameter which is influenced by one variable of a first output signal that is representative of a response of said microlever to said excitation of said lower vibration mode.
