用于岩石系外行星和稳定光谱观测的阶梯式摄谱仪 (ESPRESSO) 需要对从望远镜到摄谱仪的光路进行主动环路稳定，以实现其每秒厘米的精度目标。该任务是通过压电致动器移动沿光路放置的镜子来完成的。使用两个相机来获取视场和光瞳图像，并动态计算所需的校正并将其应用于压电。在本文中，我们将讨论 ESPRESSO 科学操作的相机使用、性能和网络带宽要求。
The Echelle Spectrograph for Rocky Exoplanets and Stable Spectral Observations (ESPRESSO) requires active-loop stabilization of the light path from the telescope to the spectrograph, in order to achieve its centimeter-per- second precision goal. This task is accomplished by moving the mirrors placed along the light path by means of piezoelectric actuators. Two cameras are used to acquire the field and pupil images, and the required corrections are dynamically calculated and applied to the piezos. In this paper we will discuss the camera usage, performance and network bandwidth requirements for the ESPRESSO scientific operations.
