Abstract

Ring aperture telescope is a new kind of telescope, it has complete U-V coverage and the limiting resolution equivalent to that of a full aperture telescope with the same diameter. There are two ring telescope proposals in China. One is 30m Ring Interferometric Telescope (RIT), its primary mirror is expected to be composed by 90 segments; another is 8m Chinese Giant Solar Telescope (CGST), its primary mirror is expected to be composed by 24 segments if segmented mirror scheme is adopted. In this paper, an overview of ring telescope and modeling for it are introduced. The main difference and characteristic in active control strategy and adaptive optics implementation between ring segmented telescope and full segmented telescope are pointed out. Detailed analysis about these two aspects are presented. The results of simulation and analysis show that the current strategies on active control and adaptive optics could meet the demand of most science cases not only in infrared waveband but also in near infrared even in visible waveband.
