Paper Abstract

For a segmented primary mirror consisting of 7 segments organized in 1 concentric hexagonal band around the central segment, of which the point spread function (PSF) is represented by the product of the grid function (GF) and the PSFj of an individual segment. The system PSF and Strehl ratio given for the cases of the gaps or piston errors are present.
