论文摘要
我们提出了一种简单的方法,用于从大型数据集中提取少量参考光学湍流和风轮廓,用于单个共轭和极端自适应光学仿真。这些参考曲线可用于缓慢的端到端自适应光学模拟,以表示大气的可变性。该方法基于以下假设:这些系统的性能与集成的大气参数$ r_0 $,$θ_0$和$τ_0$相关。配置文件是从一个大型数据集中选择的,该数据集同时符合这些参数的分布,因此代表了AO系统所见大气的可变性。我们还将等效层压缩方法扩展到包括风轮廓。该方法应用于来自ESO Paranal的立体界数据,以提取五个湍流和风谱,涵盖了大气变异性的广泛范围,我们使用分析AO模拟显示,该方法与AO校正的Strehl比率的等效范围相关。
We present a simple method of extracting a small number of reference optical turbulence and wind profiles from a large dataset for single conjugate and extreme adaptive optics simulations. These reference profiles can be used in slow end-to-end adaptive optics simulations to represent the variability of the atmosphere. The method is based on the assumption that performance for these systems is correlated with integrated atmospheric parameters $r_0$, $θ_0$ and $τ_0$. Profiles are selected from a large dataset that conform concurrently to the distributions of these parameters, and hence represent the variability of the atmosphere as seen by the AO system. We also extend the equivalent layers method of profile compression to include wind profiles. The method is applied to stereo-SCIDAR data from ESO Paranal to extract five turbulence and wind profiles that cover a broad range in atmospheric variability, and we show using analytical AO simulation that this correlates to the equivalent range of AO-corrected Strehl ratios.
