Summary
| Description |
English: Excitation and detection scheme in bimodal AFM. The cantilever is excited at its first two eigenmodes with frequencies f1 and f2. Upon interaction with the sample, the components of the tip’s response are processed. The topography is obtained by keeping A1= constant. In a bimodal AM-FM configuration, two feedback loops act on the 2nd mode. One keeps A2 fixed while a phase-lock loop keeps ϕ2=90º. |
