a Uniform circular aperture with 16 spikes in a matrix of dimensions 2048 × 2048 pixels. The average diameter = 1445 pixels. b: The diffracted image or the intensity impulse response is corresponding to the aperture of 16 spikes shown in (a). c: The Normalized PSF plot in the range from 990 up to 1058 pixels is corresponding to the image shown in the (4- a). (4- d): The Normalized PSF plot in the range from 1014 up to 1034 pixels at y = 1024 pixels is corresponding to the image show4n in (a). e: The Normalized PSF plot in the range from 1014 up to 1034 pixels at x = 1024 pixels is corresponding to the image shown in (a)
