兹维基瞬变设施观测系统(OS)是ZTF项目的数据收集器，目的是在时间域内研究天体物理现象。ZTF OS是基于南加州帕洛玛天文台的48英寸口径施密特类型设计的塞缪尔·奥辛望远镜。它包括了新的望远镜非球面校正器光学系统、圆顶和望远镜驱动器、一个大幅面曝光快门、一个平场照明系统、一个机器人带通滤光片交换器，以及关键元素：一个新的47平方度、6亿像素的低温CCD马赛克科学相机，以及支持设备。操作系统收集数字化调查数据并将其发送到ZTF数据系统(DS)。在这里，我们描述了ZTFOS的设计、光学实现、提供的图像质量、探测器性能和机器人测量效率。
The Zwicky Transient Facility (ZTF) Observing System (OS) is the data collector for the ZTF project to study astrophysical phenomena in the time domain. ZTF OS is based upon the 48 inch aperture Schmidt-type design Samuel Oschin Telescope at the Palomar Observatory in Southern California. It incorporates new telescope aspheric corrector optics, dome and telescope drives, a large-format exposure shutter, a flat-field illumination system, a robotic bandpass filter exchanger, and the key element: a new 47-square-degree, 600 megapixel cryogenic CCD mosaic science camera, along with supporting equipment. The OS collects and delivers digitized survey data to the ZTF Data System (DS). Here, we describe the ZTF OS design, optical implementation, delivered image quality, detector performance, and robotic survey efficiency.
