From: Resonant scanning design and control for fast spatial sampling
(a) Schematic of experimental set up for phase controlled resonant scanning. (b) Phase control accuracy of proposed hardware. (c) Recorded on-resonance scanning pattern, for two successive frames. (d) Recorded designed unmodulated sampling pattern, for two successive frames. (e) Recorded modulated sampling pattern with \(r \sim 2.0\). Red rectangles are the Regions-of-Interest (RoI) and black numbers indicate amount of sampling points within RoI. Compared to the reference unmodulated scanning pattern, RoI sampling density is increased by \(1.3\times \) with modulated scanning.
