Active Q Control
During AFM imaging in Non-contact and tapping imaging, especially in liquid, the kinetic energy of the cantilever is decreased due to the interaction between the cantilever and the sample. By actively compensating the energy loss, Q control enhances the quality of topographic data. Active Q control circuit also provides arbitrary phase shift of the cantilever oscillation, by which the quality factor is increased or decreased.
