Theoretical minimum uncertainty of single-molecule localizations using a single-photon avalanche diode array

Edoardo Charbon, Claudio Bruschini, Paul Mos, Arin Can Ülkü, Daniel Fan

Single-photon avalanche diode (SPAD) arrays can be used for single-molecule localization microscopy (SMLM) because of their high frame rate and lack of readout noise. SPAD arrays have a binary frame output, which means photon arrivals should be described a ...
