摘要
We propose a super-resolution technique for dense clusters of blinking emitters. The method relies on two basic assumptions: the emitters are statistically independent and a model of the imaging system is known. We numerically analyze the performance limits of the method as a function of emitter density and noise level. Numerical simulations show that five closely packed emitters can be resolved and localized to a precision of 17 nm. The experimental resolution of five quantum dots located within a diffraction-limited spot confirms the applicability of this approach. Statistical tests validate the independence of our quantum dots separated by nanoscale distances.
