Effects of Aberrations on Point Spread Function of Three Zone Aberrated Optical Imaging System with Variable Apodization





Presence of optical aberrations degrades the performance of the optical system. These effects can be reduced by inserting proper amplitude filters. In the current study, suitable amplitude-apodization pupils have been used for tailoring the point spread function (PSF), in order to attain full-width at half-maximum (FWHM) and suppressed side lobes. Intensity profiles for the unapodized and variable apodized cases have been considered. By comparing and analyzing the various PSFs, the effects induced by monochromatic aberrations such as defocusing effect, and the primary spherical aberration have been controlled for various degrees of apodization parameter β. The proposed apodizer is very effective in increasing the resolution of the optical systems.
