a Single scattering (green), multiple scattering (blue) and noise (red) rate at z = 32 mm. b Single scattering, multiple scattering, and noise rates as a function of depth. c, d Maps of local RPSFs (in amplitude) before and after correction, respectively, at three different depths (From top to bottom: z = 20 mm, 32 mm and 60 mm. Black boxes in panel (a) and (c) corresponds to the same area. e Resolution δρ(−3dB) as a function of depth. Initial resolution (red line) and its value after UMI (green line) are compared with the ideal (diffraction-limited) resolution (Eq. (5)).
