Studies of PSF Intensities of Two Zone Apertures in Spherical Aberration

Abstract: The lateral resolution of the central peak is improved by the highest degree of the amplitude apodization parameter β. The presence of first minima with zero intensity necessary for Rayleigh criterion can be used to study two-point resolution. The point spread function of the optical system in the presence of defocus and primary, secondary and tertiary spherical aberration with Hanning and Connes amplitude filter is studied. A noted increase in the profile of the point spread function has been achieved. Employment of the Hanning and Connes amplitude pupil function under the higher degree of spherical aberration and defocusing effect helps the optical systems increases the resolution.

Keywords: PSF- point spread function, amplitude apodisation, primary, secondary and tertiary spherical aberration, defocus, two-zone aperture, Hanning function, Connes function, super-resolution.
