Abstract

We present a fitter for 3D single-molecule localization of arbitrary, experimental point spread functions (PSFs) that reaches minimum uncertainty for EMCCD and sCMOS cameras, and achieves more than 10^5 fits/s. We provide tools to robustly model experimental PSFs and correct for depth induced aberrations, which allowed us to achieve an unprecedented 3D resolution with engineered astigmatic PSFs, and acquire high quality 3D superresolution images even on standard microscopes without 3D optics.

提出了一種適用于EMCCD和sCMOS攝像機的任意、實驗點擴展函數(PSFs)的三維單分子定位的方法,達到了10^5的擬合/秒。我們提供的工具是對模型實驗的PSFs和正確的深度誘發象差,這使我們能夠達到前所未有的三維分辨率的工程散光PSFs,并獲得高質量的三維超分辨率圖像,即使在標準顯微鏡,沒有三維光學。
