摘要:
本文描述了为Sunrise III气球载荷望远镜开发的波前校正和图像稳定系统(CWS),并提供了其在集成到望远镜及2024年科学飞行中的性能信息。通过相关跟踪器(CT)和快速偏折-倾斜镜,实现快速图像稳定;低阶像差如模糊和彗差由六元件谢尔曼-哈特曼波前传感器(WFS)测量并由主动望远镜次级镜进行自动聚焦和手动彗差校正。CWS被指定能够提供精度为0.005弧秒(均方根)的稳定图像。自动聚焦调整被指定以维持CWS焦点平面内的聚焦稳定性为0.01波长。
英文摘要:
This paper describes the wave-front correction and image stabilisation system (CWS) developed for the Sunrise III balloon-borne telescope, and provides information about its performance as measured during the integration into the telescope and during the 2024 science flight. The fast image stabilisation is done by a correlation tracker (CT) and a fast tip-tilt mirror, low order aberrations such as defocus and coma are measured by a six-element Shack-Hartmann wavefront sensor (WFS) and corrected by an active telescope secondary mirror for automated focus and manual coma correction. The CWS is specified to deliver a stabilised image with a precision of 0.005 arcsec (rms). The autofocus adjustment is specified to maintain a focus stability of 0.01 waves in the focal plane of the CWS.
