论文摘要
Ristretto项目的目的是建立一种可以检测到近距离球星的反射光的工具。它是一个两个阶段的仪器:可见的极端AO系统,然后是七个Spaxel单模式高分辨率光谱仪。在本文中,我们介绍了该光谱仪的设计:一种带有单模式纤维的经典梯形光谱仪。已经选择了标准的单模式纤维,并形成了长倾斜的缝隙,以便在检测器上具有正确的顺序间距。该仪器将在真空下进行热控制,以使其稳定。
The RISTRETTO project is aiming to build an instrument that will detect the reflected light from close-by exoplanet. It is a two stage instrument: An extreme AO system in the visible, followed by a seven spaxel single mode High resolution Spectrograph. In this paper we present the design of this spectrograph: a classical echelle spectrograph fed with single mode fibers. Standard single mode fibers have been chosen and are forming a long tilted slit in order to have the right order spacing on the detector. The instrument will be under vacuum and thermally controlled in order to make it stable.
