| Abstract | ||
| We have been studied the effect of central elliptical obscuration inside elliptical aperture on the point spread function(PSF) to diffraction – limited system of different values of obscurative ratios (ε=0.25,0.5,0.75) ,where the results showed that the increase of obscurative ratio yield to decrease in (PSF). Elongation ratio also was studied for elliptical aperture and elliptical obscuration on (PSF) where the elongation increment for horizontal axis (major axis) leading to significant improving in (PSF). | ||
