凯克行星探测器(KPF)是加州大学伯克利分校空间科学实验室为W.M.凯克天文台开发的一种光纤馈送、高分辨率、高稳定性的光谱仪。KPF被设计用来通过多普勒光谱来描述系外行星的特征，目标是单次测量精度为0.3m S-1或更高，然而它的分辨率和稳定性将使各种天体物理追求成为可能。在这里，我们提供了几个子系统的初步设计审查后设计更新，包括：主光谱仪、Zerodur光学工作台的制造、数据还原管道、光纤搅拌器、光缆设计、光纤扰频器、VPH测试结果和曝光计。
The Keck Planet Finder (KPF) is a fiber-fed, high-resolution, high-stability spectrometer in development at the UC Berkeley Space Sciences Laboratory for the W.M. Keck Observatory. KPF is designed to characterize exoplanets via Doppler spectroscopy with a goal of a single measurement precision of 0.3 m s-1or better, however its resolution and stability will enable a wide variety of astrophysical pursuits. Here we provide post-preliminary design review design updates for several subsystems, including: the main spectrometer, the fabrication of the Zerodur optical bench; the data reduction pipeline; fiber agitator; fiber cable design; fiber scrambler; VPH testing results and the exposure meter.
