The Benefit and Challenge of using Resonance Enhancement Resonance enhancement technique is the fastlane toward raising signal well above the noise floor to increase signal-to-noise ratio (SNR) and dynamical range. Such an approach is common for Scanning Probe Microscopy (SPM) […]

Zurich Instruments User Meeting
“Jamais 2 sans 3,” as the French say, where number three worked as a charm. For this 3rd SPM User Meeting, we were able to host the meeting in our home city and brought together more users than ever before […]

Tracking Resonance Frequency without Phase: the DFRT Method

on 18.10.2013 at 18:47 by Romain Stomp on Blog of Romain Stomp
For high Q-factor resonator (> 500), it is a common method for SPM application to use a Phase Locked Loop (PLL) to track the change in cantilever frequency: the high phase sensitivity at 90° guarantees accurate measurements and stable PID […]
