تأثير عرض المرشح الكاوسي على دالة الانتشار النقطية (PSF) لصف من الفتحات الدائرية المركبة باستخدام ضوء غيرمتشاكه

Abstract

In this research we study the effect of width Gauss Filter on the point spread function (psf)in which diffraction limited for arrays of circular synthetic in state one circular aperture which usually used in optical systems ,and we derivative the equation of point spread function (psf) for this case ,the Gaussian filter is used in different values of width for set of circular synthetic Apertures , and we found the increasing width lead to decreasing the secondary peaks for point spread function (psf) (we called this case Apodization) and this means increasing the ratio of signal to noise.
