Studies in Computational IntelligenceDue to the interaction between tip and the surface, the resonance frequency of the cantilever changes. As shown in this chapter, an attractive force between tip and sample leads to a lower resonance frequency of the cantilever, while for repulsive tip-sample forces the resonance frequency increases.

In the following we do not consider noise due to floor vibrations or sound, but more fundamental limits of noise due to thermal excitation of the cantilever, or du
