Summary of lateral and axial resolution of dual-slit confocal LSM. (a, b) Lateral resolution under different slits’ width. The colored dots in (a) denote the measured lateral intensity of beads with different slit’s width. Scale bar in (a) is 2 μm. Averaged lateral resolution with corresponding slit’s width is plotted in (b), and the red line is the fitted value. (c, d) Axial resolution under different slits’ width. Scale bar in (c) is 4 μm
