Summary
Pupilfunctionsarecompactandmodifiabledescriptionsof the
three-dimensional (3D) imaging properties of wide-field opti-
cal systems.The pupil function of a microscope can be compu-
tationally estimated from the measured point spread function
(PSF) using phase retrieval algorithms. The compaction of a
3D PSF into a 2D pupil function suppresses artefacts and
