Imaging with Hexagonal Segmented Mirror

Abstract

Different hexagons configuration aperture models of the optical telescopemirror is carefully considered in this study. The point spread function and themodulation transfer function of a reference star using different hexagonsconfiguration are computed and the quantitative assessment for the results aredescribed. It has been shown that the height of the point spread function decreasesrapidly when the area of the circular aperture of the optical telescope is 18 timesthe area of the individual hexagon to be arrange to fill this aperture. No significantchange has been noticed as the area of the this aperture exceeds 121 times the areaof the individual hexagon.
