Fig. 8From: Modeling of corona virus and its application in confocal microscopyNormalized PSF for the spiky aperture shown in the R.H.S. of (7). The radial coordinate range is from 236 up to 296 pixels of total range 60 pixels where the center is at 256 pixels. Hence, in the figure the peak is found at 22 pixels which deviate from the theoretical value by 2 pixelsBack to article page
