论文摘要
在过去的几年中，Padova的天文台（Istituto Nazionale di Astrofisica -Osservatorio Astromonico di Padova）和Padova大学都大量参与了专门用于地面和基于空间的外部搜索的项目。有关我博士学位的活动在太空项目的框架和地面仪器领域都被利用。柏拉图（Plato）是“星星的行星过渡和振荡”的首字母缩写，是一个ESA任务O，其目标是检测和表征外部行星，利用其在明亮的星星上的过境。总体仪器布局由多个望远镜概念仪器组成，由数十台望远镜单元组成，为其开发了全部反射光学解决方案。这些设备的特征是非常大的视野（一侧> 20度），其光学质量将大部分能量适合于单个传感器像素。我参加了望远镜光单元原型的组件，集成和验证（AIV），以验证AIV过程和望远镜光学性能在飞行中。 Shark-Nir是“从R到K频段的高阶自适应光学系统的冠状系统系统的首字母缩写”，是一种仪器，旨在以Coronagragraphicraphic Direct Imageing和Spectroscopic模式进行搜索和表征NIR域中的年轻外射流系统和恒星形成区域。它已被选为第二代大型双筒望远镜（LBT）仪器，它将利用LBT极端自适应光学元件（XAO）校正的出色性能，这是Shark-NIR所必需的，才能实现最佳的可造影性能，这是必须检测到围绕明亮恒星绕着明亮的恒星绕的淡淡的行星。关于鲨鱼，我的活动一直在执行仪器的光学对齐和资格。
In the last years, the Observatory of Padova (Istituto Nazionale di Astrofisica - Osservatorio Astronomico di Padova) and the University of Padova have been involved massively in projects dedicated to the exoplanets search, both ground, and space-based. The activities concerning my Ph.D. have been exploited both in the framework of the space projects and in the field of ground instrumentation. PLATO, the acronym of "PLAnetary Transits and Oscillations of stars", is a ESA mission o with the target to detect and characterize exoplanets utilizing their transit on a bright star. The overall instrumental layout consists of a multi-telescope concept instrument, composed by several tens of telescope units, for which it has developed an all-refractive optical solution. These devices are characterized by a very large Field of View (>20 degrees on one side) with an optical quality that fits most of the energy into a single sensor pixel. I participated in the Assembly, Integration, and Verification (AIV) of the Telescope Optical Unit prototype, to validate the AIV procedure and the telescope optical performance in-flight conditions. SHARK-NIR, the acronym of "System for coronagraphy with High order Adaptive optics from R to K band - Near-Infrared", is an instrument designed to search and characterize the young exo-planetary system and star-forming regions in the NIR domain, in coronagraphic direct imaging and spectroscopic mode. It has been selected for the 2nd generation Large Binocular Telescope (LBT) instruments, and it will take advantage of the excellent performance of the LBT eXtreme Adaptive Optics (XAO) correction, necessary for SHARK-NIR to achieve the best possible coronagraphic performance, which is mandatory to detect faint planets orbiting around bright stars. Concerning SHARK, my activity has been performing optical alignment and qualification of the instrument.
