Super-resolution Fluorescence Microscopy

11.2K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Area of Science:

  • Optical microscopy
  • Nanotechnology
  • Metrology

Background:

  • Localization microscopy typically extends 2D to 3D by adding engineered information and approximating optical aberration errors.
  • Intrinsic optical aberrations in microscopes are often treated as error sources, limiting imaging depth and field of view.

Purpose of the Study:

  • To invert the standard paradigm by exploiting intrinsic aberrations for enhanced 3D localization microscopy.
  • To develop a method for accurate 3D localization of single emitters across ultrawide and deep fields.
  • To enable precise 3D measurements of microscale systems with six degrees of freedom.

Main Methods:

  • Comprehensive calibration of an ordinary microscope to leverage latent information from intrinsic aberrations.
  • Introduction of a synergistic concept of rigid transformation for multiple 3D emitter positions.
  • Application to microscale bodies, including imaging substrates and microelectromechanical systems.

Main Results:

  • Accurate 3D localization of single emitters throughout an ultrawide and deep field of view.
  • Improved precision and testing accuracy in 3D measurements.
  • Successful elucidation of the performance and reliability of complex microelectromechanical systems.

Conclusions:

  • Intrinsic aberrations can be transformed from a challenge into an opportunity for accurate and complete localization microscopy.
  • The developed method enables precise 3D spatial information extraction from microscale objects.
  • This approach enhances the capabilities of localization microscopy for advanced metrology and microsystem analysis.
