摘要	The active control of 30-m ring interferometric telescope needs edge sensing and tip sensing when its primary mirror is composed by trapezoid-shaped segments, and the imaging performance of the RIT is determined by the accuracy of these two detecting approaches. Considering the detecting accuracy available in current segmented telescope active control systems, tire effect of these detecting approaches on the surface error of the RIT primary mirror is calculated from the point of error propagation. The corresponding effect on imaging performance (modulation transfer functions (MTFs) and point; spread functions (PSFs) at several typical wavelengths) of the RIT primary mirror is also simulated. The results show that tip sensing is very important. for increasing the active control quality of the RIT primary mirror under the present techniques.
