论文摘要
Ingot WFS是一种类似金字塔的WFS，已提议缓解LGS斑点伸长率。实际上，人造源被限制在钠层的激发雪茄形区域中，望远镜光圈的一部分具有相应的不同透视图。这种多样性会根据照明的子孔位位置产生WFS响应的变化。 Ingot WFS的可行性研究正在毛里项目中发展。在这项工作中，我们介绍了构建的数值模拟器，以研究Ingotwfs的性能，以Strehl比率来研究，并以闭环方式以模态方法重建了传入的湍流波前。我们还讨论了我们做出的假设和测试，以探索在游戏中扮演关键角色的参数范围。最后，我们报告了在不同条件和输入畸变下，Ingot WFS预期的性能的仿真总体结果，目的是将测量的AO循环残留物与Shack-Hartmann WFS的拟合物进行比较，并在相同的假设下获得了工作。
The Ingot WFS, a Pyramid-like WFS, has been proposed as a relief to the LGS spot elongation. Actually, the artificial sources are confined in an excited cigar-shaped region in the sodium layer and portions of the telescope aperture have a corresponding different perspective. This diversity generates a variation of the WFS response depending on the illuminated sub-aperture position. The feasibility study of the INGOT WFS is developing within the MAORY project. In this work we present the numerical simulator built in order to investigate the performance of the IngotWFS in terms of Strehl Ratio, obtained reconstructing the incoming turbulent wavefront with a modal approach, in a closed-loop fashion. We also discuss the assumptions and tests we made in order to explore the range of parameters that play key roles in the game. Finally, we report on the overall results of the simulations of the performance expected by the Ingot WFS, under different conditions and input aberrations, with the aim to also compare the measured AO loop residuals with the Shack-Hartmann WFS ones, obtained working under the same assumptions.
