论文摘要
为了应对激光导恒星（LGS）的几何特性，已提出了Ingot波前传感器（I-WFS）作为可能的瞳孔平面WFS。在此类WFS的研究和开发中，在Maory项目的框架中，I-WFS模拟的最终目的是估算其在波前畸变测量能力方面的性能。该分析的第一步是将传入的波前转换为由光学系统产生的三个学生图像。 Ingot光学元件的固有几何特性，设计为与LGS伸长图像结合，使系统在概念上相对于其他学生WFS（例如金字塔WFS，P-WFS，p-WFS）也与在文献中可以找到的模拟技术相对于要选择的模拟技术而言。在本文中，我们旨在报告导致选择INGOT瞳孔图像模拟的射线追踪方法的考虑和推导，以及为优化计算时间的几何假设和方法。
The ingot wavefront sensor (I-WFS) has been proposed, for ELT-like apertures, as a possible pupil plane WFS, to cope with the geometrical characteristics of a laser guide star (LGS). Within the study and development of such a WFS, on-going in the framework of the MAORY project, the final purpose of the I-WFS simulation is to estimate its performance in terms of wavefront aberration measurement capability. The first step of this analysis is to translate incoming wavefronts into the three pupil images, produced by the optical system. The intrinsic geometrical characteristics of the ingot optical element, designed to be coupled with the LGS elongated image, make the system conceptually different with respect to other pupil WFSs (like the Pyramid WFS, P-WFS) also in terms of the simulation technique to be selected, within the ones which can be found in literature. In this paper, we aim to report the considerations and derivations which led to the selection of a ray-tracing method for ingot pupil images simulation, and the geometrical assumptions and approach made to optimize the computing time.
