Three Dimensional Source Localization via Pupil Phase Engineering

Single particle localization to ultra-high, sub-wavelength precision in all three dimensions is rapidly becoming an important tool for super-resolution, nano-metric imaging microscopy of cellular and protein structures. A useful approach for achieving such 3D super-localization employs novel point-spread function (PSF) designs achieved by means of pupil-phase engineering. I will discuss some of these approaches, focusing primarily on my own work on rotating PSF (RPSF) design using certain spiral-phase distributions in the imaging aperture. Such RPSFs can be employed equally effectively both in microscopy and telescopic imaging, as I would like to argue based on the results on my theoretical treatment of the source localization problem in the two settings.
