Abstract
To realize direct image of faint object which is in the close proximity of very bright object could be technologically feasible by introducing asymmetric apodization. The point spread function (PSF) of an optical system with asymmetric apodization has been found to possess a so‐called good side and a bad side. The good‐side has decreased side lobes whereas the bad‐side shows increased side lobes. This has been observed when the aperture is divided into three parts viz. two semi‐circular edge rings and a central region with an apodizer. The asymmetry in the PSF has been found to increase with the width of the edge rings and is seen to decrease with the increased apodization of the central region.
