摘要：

We study the effect of Gaussian filter on the point spread function (psf) for a single hexagonal aperture for diffraction limit system and by inserting a coma aberration (w31=0.25 and 0.5). Also we derived the point spread function for a single hexagonal aperture and when there is a Gaussian filter with different values in width used. the different values of coma aberration was study,we notice a decrease in intensity and secondary peaks of psf. The pulse to noise ratio increases with the width of the Gaussian filter increases.
