论文摘要
本文介绍了一个正在进行的项目的状态,该项目旨在为自适应光学(AO)观察开发PSF重建软件。特别是,我们首次测试了我们算法上金字塔波 - 前传感器数据的实现。作为评估其可靠性的第一步,我们使用两组独立的观测值将软件应用于明亮的,轴上的,类似点状的来源,这些观测值是通过单偶联的AO升级来获得的,用于大型双眼望远镜。仅使用遥测数据,我们通过仔细校准仪器响应来重建PSF。首先使用经典指标对结果的准确性进行了评估:具体来说,重建的PSF与观察到的PSF的差异为少于2%的StreHL比,全宽度为4.5%,最大为一半。此外,在最坏情况下,与PSF核心相关的回收的环绕能量在4%的水平上是准确的。然后,通过考虑一个理想化的科学测试案例来评估重建的PSF的准确性,该测试案例由紧凑型星系的形态学参数进行测量组成。将来,我们的项目将包括对各个行星,低SNR制度的分析以及对多偶联的AO观察的应用。
This paper presents the status of an ongoing project aimed at developing a PSF reconstruction software for adaptive optics (AO) observations. In particular, we test for the first time the implementation of pyramid wave-front sensor data on our algorithms. As a first step in assessing its reliability, we applied the software to bright, on-axis, point-like sources using two independent sets of observations, acquired with the single-conjugated AO upgrade for the Large Binocular Telescope. Using only telemetry data, we reconstructed the PSF by carefully calibrating the instrument response. The accuracy of the results has been first evaluated using the classical metric: specifically, the reconstructed PSFs differ from the observed ones by less than 2% in Strehl ratio and 4.5% in full-width at half maximum. Moreover, the recovered encircled energy associated with the PSF core is accurate at 4% level in the worst case. The accuracy of the reconstructed PSFs has then been evaluated by considering an idealized scientific test-case consisting in the measurements of the morphological parameters of a compact galaxy. In the future, our project will include the analysis of anisoplanatism, low SNR regimes, and the application to multi-conjugated AO observations.
