摘要

新一代陆基超大望远镜采用自适应光学技术。许多AO系统需要重建湍流剖面,这被称为大气层析成像。由于望远镜尺寸的增长,这一问题的计算负荷急剧增加。因此,最先进的实时硬件与利用可用硬件资源的高效求解器的协作是非常重要的。在这次演讲中,我们将介绍一种称为FEWHA的迭代方法,以及它在实时硬件上的最佳表现。最后,我们比较了FEWHA和在MAORY框架内经常使用的MVM。

Performance of an iterative solver for atmospheric tomography on real-time hardware
The new generation of ground-based extremely large telescopes rely on adaptive optics (AO). Many AO systems require the reconstruction of the turbulence profile, which is called atmospheric tomography. Due to the growth of telescope sizes the computational load for this problem is increasing drastically. Thus, the collaboration of state-of-the-art real-time hardware with an efficient solver that take advantage of the available hardware resources is of great importance. In this talk, we look at an iterative approach called FEWHA and its adaption to perform best on real-time hardware. We conclude our talk with a comparison between FEWHA and the frequently used MVM within the framework of MAORY.
