作为凯克行星探测器项目的一部分,已经安装了一个光纤注入单元,并将部署在凯克Ⅰ望远镜上,目的是向凯克行星探测器仪器和伴随的H&K光谱仪提供色散补偿和倾斜/倾斜校正的光。KPF的目标是通过径向速度技术表征系外行星,单次测量精度为30厘米/S或更高。为此,FIU必须为Science和钙质H&K纤维提供稳定的F数和主射线角。我们的设计方法是对Science和钙质H&K臂使用具有大气色散补偿的平面光学布局。利用SWIR导引相机和压电尖/倾斜镜使目标保持在光纤的中心。
As part of the Keck Planet Finder (KPF) project, a Fiber Injection Unit (FIU) was implemented and will be deployed on the Keck Ⅰ telescope, with the aim of providing dispersion compensated and tip/tilt corrected light to the KPF instrument and accompanying H&K spectrometer. The goal of KPF is to characterize exoplanets via the radial velocity technique, with a single measurement precision of 30cm/s or better. To accomplish this, the FIU must provide a stable F-number and chief ray angle to the Science and Calcium H&K fibers. Our design approach was use a planar optical layout with atmospheric dispersion compensation for both the Science and Calcium H&K arms. A SWIR guider camera and piezo tip/tilt mirror are used to keep the target centered on the fibers.
