Low Latency Demodulation for High-Frequency Atomic Force Microscopy Probes

One prerequisite for high-speed imaging in dynamic-mode atomic force microscopy (AFM) is the fast demodulation of the probe signal. In this contribution, we present the amplitude and phase estimation method based on the acquisition of four points per oscillation, with the sampling frequency being ph...
