宽视场自适应光学系统的性能取决于输入设计参数。在这里，我们研究的性能的多共轭自适应光学系统设计的欧洲极大望远镜，使用端到端的蒙特卡罗自适应光学仿真工具，DASP（达勒姆自适应光学仿真平台）。我们考虑的参数，如激光引导星的数量，钠层的深度，波前传感器的像素规模，变形镜（DM）的数量，镜共轭和致动器间距。我们提供可以节省成本的潜在领域，并研究性能和成本之间的权衡。我们的结论是，一个六激光制导星星系统使用三个DM似乎是一个甜蜜点的性能和成本的妥协。
The performance of a wide-field adaptive optics system depends on input design parameters. Here we investigate the performance of a multiconjugate adaptive optics system design for the European Extremely Large Telescope, using an end-to-end Monte Carlo adaptive optics simulation tool, DASP (Durham adaptive optics simulation platform). We consider parameters such as the number of laser guide stars, sodium layer depth, wavefront sensor pixel scale, number of deformable mirrors (DMs), mirror conjugation and actuator pitch. We provide potential areas where costs savings can be made, and investigate trade-offs between performance and cost. We conclude that a six-laser guide star system using three DMs seems to be a sweet spot for performance and cost compromise.
