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