摘要

摘要: 为了评价地基大口径望远镜对空间目标自适应光学系统校正后的实际分辨率，提出了可分辨单元数比指标。结合1.23 m自适应光学望远镜的观测数据，对可分辨单元数比的物理意义、适用范围、误差影响因素以及大气弥散的影响进行了分析。结果表明：可分辨单元数比能全面反映望远镜系统对空间目标自适应校正后的实际分辨率，且物理意义更直观；适用于所有可获取波前特征的望远镜自适应校正后实际分辨率的评估；其误差主要依赖于波前探测器的测量误差；大气弥散对其影响可忽略。

Abstract: A new index, Resolved Cells Ratio(RCR), was proposed to evaluate the actual resolution of ground-based large-aperture telescope for spatial objective observation after adaptive optical system partial correcting. We discussed the physical meaning of the RCR combined with the observation instances of the 1.23 adaptive optical telescope. The range of the application of the RCR, the error influence factors and the effect of the atmospheric dispersion on the RCR were also analyzed. The result shows that the RCR could completely reflect the correction effectiveness of the adaptive optical telescope and the physical meaning of the RCR was intuitive. RCR can be applied to the estimation of the correction effectiveness of a telescope that can get the characterization of the wavefront. The error of the RCR mainly depend on the measurement error of the wavefront sensor. The effect of atmospheric dispersion on the RCR can be neglected.
