Correction of a Depth-Dependent Lateral Distortion in 3D Super-Resolution Imaging
(Top row) Raw data shown at three different axial depths and corresponding wobble curves. (Middle) Phase-retrieved PSF (PR-PSF) at three axial depths and corresponding wobble curves, which are in good agreement with the raw data. (Bottom) PR-PSF with only rotationally symmetric Zernike modes. Resulting wobble calibration shows an absence of the wobble distortion.
