摘　　要：讨论了使用S H方法校正LAMOST望远镜像质时对覆盖完备性的影响 ;提出了两种覆盖完备性的检验方法 ,并使用Tycho 2星表做了覆盖完备性计算 ;分析了使用不同亮度的星作S H检验时的覆盖率 ;给出了为满足LAMOST覆盖要求所需的SThe Shack-Hartmann(S-H) method, a common technology for measuring the ray aberrations of mirrors and lenses,was be used in LAMOST to improve image quality. A quite bright star is required in the center of view field of the telescope when S-H method is used and it will bring the blind area if the brightness of the S-H star is limited. In this paper, the effect of S-H on sky tiling is analyzed and the completeness of tiling is calculated based on Tycho-2 star table.

关 键 词：主动光学 S-H检验 覆盖
