Modeling of corona virus and its application in confocal microscopy
Hamed, Abdallah;
Abstract
Abstract
Background: The proposal of spiky apertures showed resolution improvement compared with the circular apertures.
Three models of corona virus are given. The 1st model consists of uniform circular aperture provided with 8 spikes
while the 2nd model has 16 spikes for the same uniform circular aperture. The 3rd model has circular linear distribu tion with 8 spikes.
Results: The Normalized Point Spread Function (PSF) or the impulse response is computed for the three models
using fast Fourier transform technique. In addition, the autocorrelation function corresponding to these apertures is
calculated and compared with that corresponding to the ordinary circular and conic apertures. Coronavirus image
is used as an object in the formation of images using confocal scanning laser microscope provided with suggested
models. The fabricated MATLAB code is used to compute and plot all images and line plots.
Conclusions: The PSF plots are computed from Eqs. (8) and (12) using MATLAB code showing narrower cut-off in the
PSF for spiky aperture compared with that corresponding to the uniform circular aperture and modulated linear and
quadratic apertures. Hence, I reached resolution improvement in the case of spiky aperture
