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