Paper Abstract
We present our studies on apodization of pupils with various amplitude filters with respect to images of point
objects. The central intensity distribution, first maxima and first minima are compared with and without
apodisation. The effects of aberrations and aperture obscuration are also studied. It is shown that in certain
cases, the aberrated images can be improved with the help of suitable amplitude filters.
