AI 中文摘要
Seidr是Asgard套件中的新型干涉光束组合器，利用甚大望远镜干涉仪中Bifrost仪器的通用基础设施。它将混合模式选择性光子灯笼注入模块与内核零化光子芯片后端相结合，实现对系外行星、系外卫星和系外黄道尘埃的深H波段零化高对比度研究。本文更新总结了Seidr当前的设计成熟度和点源到灯笼输出的近期模拟。我们还概述了基于神经网络的波前估计方案的进展，该方案利用光子灯笼输出感知相位波动，旨在反馈到Baldr的可变形镜并改善零化光注入。
英文摘要
Seidr is a new interferometric beam combiner within the Asgard Suite, utilizing infrastructure common to the BIFROST instrument at the Very Large Telescope Interferometer. Seidr combines hybrid mode-selective photonic lantern injection modules with a kernel-nulling photonic chip backend to enable deep H-band nulling for high-contrast studies of exoplanets, exomoons, and circumstellar dust. This instrument update summarizes Seidr's current design maturity and recent simulations of the point source - to - lantern outputs. We also outline progress on our neural network-based wavefront estimation scheme, which uses the photonic lantern outputs to sense phase fluctuations, designed to feed back to Baldr's deformable mirror, and improve nuller light injection.
