AI 中文摘要
iLocater是一台将于2026年夏季交付给大双筒望远镜的新型近红外超高精度视向速度（EPRV）仪器，该仪器利用单模光纤（SMF）进行光传输，包括其校准系统。本文概述了iLocater校准系统，详细说明了将校准光注入SMF所需的特定光源和硬件，还讨论了可在这些光源间高效切换并将光分配到仪器所有必要位置的硬件，完全消除了对自由空间传输的需求。
英文摘要
iLocater is a new near-infrared, extreme precision radial velocity (EPRV) instrument delivered to the Large Binocular Telescope in the summer of 2026. The instrument utilizes single-mode fibers (SMFs) for light transmission, including its calibration systems. We present an overview of the iLocater calibration system, detailing the specific sources and the hardware required to inject calibration light into the SMFs. Furthermore, we discuss the hardware that efficiently switches between these sources and distributes the light to all necessary instrument locations, entirely eliminating the need for free-space propagation.
