Engineering of Aberrated PSF by Asymmetric Apodization with the Complex Shaded Aperture

The point spread function (PSF) produced by a coherent optical system under the influence of defocus, coma, and primary spherical aberration (PSA) is examined in this work. This paper deals with asymmetric apodization pupil engineering to control monochromatic aberrations. To reduce aberrations on diffracted PSF, approach uses amplitude phase apodization. Analytical investigations intensity PSF are carried out varying amounts degrees Computed central peak full width at half maxima (FWHM) analyzed. resolution diffraction-limited imaging improved using an filter that minimizes effect defocus.
