Paper Abstract

Segmented deployable primary mirror is an effective way to increase the size of primary mirror to get higher resolution. We explore research on primary mirror with 8 quasi annulus sectors surrounding an octagon central segment, which is quite different to generally used structure with regular hexagon segments. The PSF of quasi annulus sector is deduced in this paper which hasn't been mentioned before. The expression of total primary mirror is described and diffraction effect on image quality with gaps and piston is discussed and simulated.
