摘要：

The presence of optical aberrations degrades the performance of an 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 various PSFs, the effects induced by monochromatic aberrations such as the defocusing effect, and primary spherical aberration have been controlled for various degrees of apodization parameter beta. The proposed apodizer is very effective in increasing the resolution of optical systems.
