英文摘要	As the design and assembly of optical systems in an optical telescope with large aperture mirrors are related to the mirror seeing, this paper introduces the normalized point source sensitivity (PSSn) to improve the limitation of traditional evaluation method and to realize the evaluation of mirror seeing in all frequencies. The concepts of the mirror seeing and its detection and evaluation methods were introduced and the shortcomings of the traditional evaluation methods and evaluation factors were pointed out. The evaluation index PSSn proposed by the 30 m large aperture telescope research group was introduced the new evaluation method. The PSSn properties were analyzed, and the expressions of the PSSn in different exposure conditions and seeing conditions were obtained based on the multiplication property and exposure conditions of the PSSn. The calculation procedure was given by considering the shutter time, mirror figure and atmosphere turbulence. Finally, with the help of random selection of sub-aperture on a large aperture wavefront, the `frozen turbulence' was used to generate the simulated seeing condition over the mirror surface. The evaluation procedure was verified by this simulation. Based on the evaluation and analysis method presented in this paper, the system engineers could evaluate the mirror seeing for the large aperture optical system more objectively, and could build the error budget tree more reasonably to decrease the cost of the optical system. 2016, Science Press.
