论文摘要
通过自适应光学支撑的仪器进行的科学观察的优化和调度可以大大受益于PSF功绩(FWHM,Strehl比率,环绕能量和对比度)的预测,这取决于AO仪器,在观察夜期间的科学目标和湍流条件。在这项贡献中,我们探讨了预测最有用的PSF(SR和FWHM)中的一些可能性。为了实现这一目标,我们将在短时间内中尺度大气模型Astro-Meso-NH预测的光学湍流作为针对特定AO仪器开发和量身定制的PSF仿真软件的输入。将通过使用SCAO System Soul(FLAO升级)在LBT和Saxo上供应相机LUCI的SCAO System Soul(FLAO升级)在特定目标上获得的Sky测得的PSF值进行比较,将进行初步验证。这项研究将为实施在现有大气的运营预测系统(湍流和大气参数)基础上实施这种优点的运营预测铺平道路。在这项贡献中,我们将注意力集中在PSF上轴上的预测上。
The optimization and scheduling of scientific observations done with instrumentation supported by adaptive optics could greatly benefit from the forecast of PSF figures of merit (FWHM, Strehl Ratio, Encircle Energy and contrast), that depend on the AO instrument, the scientific target and turbulence conditions during the observing night. In this contribution we explore the the possibility to forecast a few among the most useful PSF figures of merit (SR and FWHM). To achieve this goal, we use the optical turbulence forecasted by the mesoscale atmospheric model Astro-Meso-NH on a short timescale as an input for PSF simulation software developed and tailored for specific AO instruments. A preliminary validation will be performed by comparing the results with on-sky measured PSF figures of merit obtained on specific targets using the SCAO systems SOUL (FLAO upgrade) feeding the camera LUCI at LBT and SAXO, the extreme SCAO system feeding the high resolution SPHERE instrument at VLT. This study will pave the way to the implementation of an operational forecasts of such a figure of merits on the base of existing operational forecast system of the atmosphere (turbulence and atmospheric parameters). In this contribution we focus our attention on the forecast of the PSF on-axis.
