Effect of hexagonal synthetic aperture on the optical system with focal error

Abstract We introduce a new approach by using hexagonal synthetic aperture in an optical system and obtaining high-resolution image. This paper illustrates two cases of with where the study was included, First, effect on diffraction-bound system, Second, focal error 25 ? 50 . The results showed significant improvement central intensity, clear decrease secondary peaks, width intensity curve, which gives image as result improving signal to noise ratio.
