摘要: 基于频谱滤波理论和经典大气湍流 7 层模型, 通过地表层自适应光学 (GLAO) 系统的理论滤波器模型, 结合 有限导星条件下的误差传递函数 (ETF), 探究了不同导星数量与不同导星排布情况下地表层自适应光学系统的性能。 研究结果表明 6 颗导星呈中心 1 颗、其余 5 颗在视场边缘均匀环形分布时, 系统校正性能较优。该研究结果对正在研 制的一米新真空太阳望远镜多层共轭自适应光学 (MCAO) 系统 (含有 GLAO 系统) 具有重要指导作用和参考价值。

Abstract: Based on the theory of spectral filtering and the classical 7-layer model of atmospheric turbulence, the performance of the adaptive optics system on ground layer under different number of guide stars and different guide star arrangements is explored by using the theoretical filter model of the Ground Layer Adaptive Optics (GLAO) system and the error transfer function (ETF) under the condition of finite guide stars. The results show that when 1 guide star is in the center and the other 5 guide stars are evenly distributed around the edge of the field of view, the calibration performance of the system is the best. The research results have important guiding role and reference value for the multi-conjugate adaptive optics (MCAO) system (including GLAO system) of the one-meter new vacuum solar telescope being developed.
