Method for assessing the spatiotemporal resolution of structured illumination microscopy (SIM)

open access: yesBiomedical Optics Express, 2021
A method is proposed for assessing the temporal resolution of structured illumination microscopy (SIM), by tracking the amplitude of different spatial frequency components over time, and comparing them to a temporally-oscillating ground-truth. This method is used to gain insight into the performance limits of SIM, along with alternative reconstruction ...
