Optical Diffraction Tomography Meets Fluorescence Localization Microscopy

18 Jul 2023  ·  Thanh-an Pham, Emmanuel Soubies, Ferréol Soulez, Michael Unser ·

We show that structural information can be extracted from single molecule localization microscopy (SMLM) data. More precisely, we reinterpret SMLM data as the measures of a phaseless optical diffraction tomography system for which the illumination sources are fluorophores within the sample. Building upon this model, we propose a joint optimization framework to estimate both the refractive index map and the position of fluorescent molecules from the sole SMLM frames.
