使用模拟的天空性能优化天文光子空间重定格式器
Optimizing astrophotonic spatial reformatters using simulated on-sky performance
摘要：
在天文仪器中最有用的技术之一是图像切片。它使光谱仪具有更紧凑的角度狭缝，同时保持吞吐量并提高分辨率。像光子灯笼和光子重新格式化器这样的天文光子组件可以用来取代迄今为止使用的大体积光学器件。本研究使用端到端模拟来近似真实的天空条件，研究此类设备的性能。它调查现有的组件，试图优化其性能，并旨在更好地了解如何最好地设计仪器，以最大限度地提高其性能。这项工作补充了该领域最近的工作，并提供了新组件的性能估计。
英文摘要：
One of the most useful techniques in astronomical instrumentation is image slicing. It enables a spectrograph to have a more compact angular slit, whilst retaining throughput and increasing resolving power. Astrophotonic components like the photonic lanterns and photonic reformatters can be used to replace bulk optics used so far. This study investigates the performance of such devices using end-to-end simulations to approximate realistic on-sky conditions. It investigates existing components, tries to optimize their performance and aims to understand better how best to design instruments to maximize their performance. This work complements the recent work in the field and provides an estimation for the performance of the new components.
