Cross-sectional imaging of a fast-moving object. a) Inpainted images at 5.3 kHz and 1.6 kHz (3 scan and 10 scan accumulations, respectively) at three different time points, showing the axial movement of the oscillating mirror (Visualization 5 (125.4KB, avi) and Visualization 6 (43.8KB, avi) ). The axial scan range was 12 µm and the mirror translation distance was 10 µm. b) A plot of the axial position of the mirror over time (blue). Three regions, initial acceleration, cruising at constant speed, and deceleration, with different curve slopes are highlighted. Scale bar 1 µm, excitation wavelength at 640 nm, xz pixel size 0.041 × 0.34 µm3, fTAG = 457755 Hz, Lissajous period 2π/3.
