Abstract

Apodization is the significant modification of the impulse response of the optical system. This modification plays a vital role in improving the imaging and focusing characteristics foe various optical systems. We present our studies on apodization of pupils with amplitude filter respect to images of point objects . The central intensity distribution, the Full width at half maximum (FWHM)of point spread function, first maxima and first minima are evaluated and compared with and without apodisation .our results shown that the resolution of the intensity of the PSF has been modified as the degree of apodization increases .
