To develop a high-speed multiresolution scanning probe microscopy trajectory based on Lissajous patterns that avoids resonant mode excitation.
Actuated a microscope scanner using two single-tone harmonic waveforms with constant frequency and amplitude.
Developed a mathematical framework to tune the spatial and temporal resolution of Lissajous trajectories.
Tested the scanning trajectory experimentally on a custom-built atomic force microscope.
Prevented unwanted scanner resonant modes and measurement noise amplification due to the narrow frequency spectrum of harmonic actuation.
Enabled rapid multiresolution imaging to obtain preview scans in a fraction of total acquisition time.
Demonstrated real-time atomic force microscopy scanning at an imaging rate of 1 frame s⁻¹.
