WebAug 5, 2008 · In the case thermal excitation [7, 8], the cantilever response or thermal noise is the result of random collisions from the Brownian motion of the surrounding fluid molecules. In this technique, the cantilever is excited directly and consequently a smooth vibration response, related only to the properties of the cantilever and the fluid, is ... WebFeb 27, 2024 · In photoinduced force microscopy (PIFM), amplitude modulation techniques, such as direct mode, and heterodyne amplitude modulation techniques have been used to detect the photoinduced force. These amplitude modulation techniques are affected by other forces because the resonance frequency shifts and nonconservative force damp the …
