Super-resolution Fluorescence Microscopy

Super-resolution Fluorescence Microscopy

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...

Conventional transient-radiation-fields-based Microwave Staring Correlated Imaging (MSCI) suffers from system complexity and modeling errors due to individual transmitter control and random frequency-hopping waveforms.

These errors degrade computational accuracy and hinder precise calibration, limiting imaging performance.
