SOUL + LUCI LBT数据的点扩散函数重建
Point spread function reconstruction for SOUL+LUCI LBT data
摘要：
本文介绍了一个正在进行的项目，旨在开发一个PSF重建软件的自适应光学（AO）的意见。特别是，我们第一次测试金字塔波前传感器数据对我们的算法的实施。作为评估其可靠性的第一步，我们将该软件应用于明亮的，轴上，点状源使用两组独立的观测，获得与单共轭AO升级的大型双目望远镜。仅使用遥测数据，我们通过仔细校准仪器响应来重建PSF。结果的准确性已首先使用经典度量进行评估：具体地说，重建的PSF不同于所观察到的小于2%的斯特列尔比和4.5%的半高全宽。此外，在最坏情况下，与PSF核心相关的回收环绕能量准确度为4%。重建的PSF的准确性，然后通过考虑一个理想化的科学测试的情况下，包括在一个紧凑的星系的形态参数的测量进行了评估。在未来，我们的计划将包括分析非等晕性，低信噪比制度，和应用到多共轭AO观测。
英文摘要：
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.
