PSFSim是一种物理正向模拟工具，通过光线追踪计算罗曼空间望远镜WFI的PSF并考虑探测器效应，支持扰动添加，可用于调试中的光学鬼像、像差测量和偏振研究。
AI 中文摘要
我们提出了一种新工具，用于在南希·格蕾丝·罗曼空间望远镜的宽视场仪器（WFI）中生成模拟点扩散函数（PSF）。该模拟工具采用物理正向方法，对仪器的光学系统进行光线追踪以计算PSF，同时考虑各种探测器效应。该工具还具有向光学系统和探测器添加扰动的能力。我们探索了该工具在望远镜调试期间可能出现的几种应用，包括光学鬼像、从衍射尖峰测量光学像差，以及研究镜面偏振的影响。
英文摘要
We present a new tool for generating simulated point spread functions (PSFs) in the Wide Field Instrument (WFI) of the Nancy Grace Roman Space Telescope. The simulation tool is physics forward, and performs a raytrace of the optical system of the instrument to compute the PSF, while also accounting for various detector effects. The tool also has the capability to add perturbations to the optical system and detectors. We explore several applications of the tool that may arise during the commissioning of the telescope, including optical ghosts, measuring the optical aberrations from diffraction spikes, and studying the effect of mirror polarization.
