摘要:

本文介绍了为日出气球望远镜研制的波前校正系统,并提供了有关其飞行性能的信息。对于低阶像差的校正,使用相关波前传感器(CWS)。它包括一个六元件夏克-哈特曼波前传感器(WFS),一个快速倾斜镜的图像运动补偿,和一个主动望远镜次镜的焦点校正。CWS提供了一个稳定的图像精度为0.04 arcsec(rms),只要粗指向优于90 arcsec峰峰值。自动聚焦调节在CWS的焦平面中保持0.01波的聚焦稳定性。在5.5天的飞行中,在33小时内获得了良好的图像质量和稳定性,包含45个持续10到45分钟的序列。

英文摘要:

This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and provides information about its in-flight performance. For the correction of low-order aberrations, a Correlating Wave-Front Sensor (CWS) was used. It consisted of a six-element Shack-Hartmann wave-front sensor (WFS), a fast tip-tilt mirror for the compensation of image motion, and an active telescope secondary mirror for focus correction. The CWS delivered a stabilized image with a precision of 0.04 arcsec (rms), whenever the coarse pointing was better than 90 arcsec peak-to-peak. The automatic focus adjustment maintained a focus stability of 0.01 waves in the focal plane of the CWS. During the 5.5 day flight, good image quality and stability was achieved during 33 hours, containing 45 sequences that lasted between 10 and 45 minutes.
