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.

提出了一种适用于EMCCD和sCMOS摄像机的任意、实验点扩展函数(PSFs)的三维单分子定位的方法,达到了10^5的拟合/秒。我们提供的工具是对模型实验的PSFs和正确的深度诱发象差,这使我们能够达到前所未有的三维分辨率的工程散光PSFs,并获得高质量的三维超分辨率图像,即使在标准显微镜,没有三维光学。
