Abstract
Binary polar Walsh filters derived from two dimensional polar Walsh functions provides an effective tool for tailoring the three dimensional intensity distributions of a point spread function (PSF) in the pupil plane in a diffraction limited imaging system. This paper reports the study of radial as well as azimuthally variant polar Walsh filters and observation on their imaging characteristics near the focal plane of a rotationally symmetric imaging system.
