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.
