Figure 2: Focus quality. Representative images from the three tissues used in this study at various focal height errors. Best = the ideal focal plane from the ground truth data set. Mean error = the focal plane at the mean focal error of the dynamic scanning system (0.3 μm from best focus). DoF = at the system's theoretical depth of field (±0.8 μm). 2 × DoF = twice the system's theoretical depth of field (±1.6 μm)
