AI 中文摘要
系外行星的高对比度成像受准静态散斑限制，现有后处理方法仍高于理论噪声极限。本文研究一种新框架，将自适应光学（AO）波前传感器遥测数据，结合ERIS涡 coronagraph的可微光学模型纳入后处理。作为首个概念验证，我们将AO遥测注入ERIS正向模型，评估其再现空中点扩散函数（PSF）的能力。研究发现，科学相机与AO遥测间的抖动差异阻碍了PSF的准确重建，本文提出了表征该抖动并确定其机械起源的计划。
英文摘要
High-contrast imaging of exoplanets is limited by the presence of quasi-static speckles and existing post-processing methods remain above the theoretical noise limit. We investigate a novel framework that incorporates adaptive optics (AO) wavefront sensor telemetry into post-processing using a differentiable optical model of the ERIS vortex coronagraph. As a first proof of concept, we inject AO telemetry into an ERIS forward model and assess its ability to reproduce the on-sky point spread function (PSF). We find that jitter discrepancies between the science camera and the AO telemetry hinder accurate PSF reconstruction. We proposed a plan to characterise this jitter and find its mechanical origin.
