Bidirectional raster scanning (BRS) with triangle voltage drive waveforms. (a) Representative triangle scanning voltage waveform. (b) Two-dimensional raster scan pattern. L: scan length; T: triangle waveform period; Vtrig: scan velocity; ∆x: sampling pitch along x (fast) scan axis; ∆y: sampling pitch along y (slow) scan axis. The raster scan pattern illustration is undersampled along y for clarity.
