TMT激光导引星系统设计
Design of the TMT laser guide star facility
摘要
激光导引星系统(LGSF)是美国30 m望远镜(TMT)的组成部分之一,在满足TMT对科学目标高分辨力成像和光谱探测的性能需求方面,LGSF 具有重要的作用。LGSF 主要负责为窄视场红外自适应光学系统(NFIRAOS)和下一代TMT-AO 系统提供人造钠导星。本文主要讨论LGSF 以下几部分:设计概述,LGSF 星群模式,LGSF 波前误差分配,发射系统设计。
Abstract
The laser guide star facility (LGSF) is an integral component of thirty meter telescope (TMT), and is of critical importance in enabling TMT to achieve the performance required to meet the Science Requirements for high resolution imaging and spectroscopy. The LGSF is responsible for generating the artificial LGS required by narrow field infrared adaptive optics system (NFIRAOS) and by the next generation of the thirty meter telescope (TMT) AO systems. The following sections will discuss the LGSF’s: design overview, LGSF asterisms, wavefront error budget and Laser Launch Telescope design.
