摘要
Dispersed Rayleigh Interferometry has been verified a potential way to co-phasing segmented mirror in orbit using natural star as beacon. Measurement error caused by background star around beacon is analyzed under specific system parameters, and tolerances of magnitude difference in two orthogonal directions are also presented. To achieve 10nm / 20nm accuracy, minimum magnitude difference of background star and beacon star is about 2.5M / 1.7M. Furthermore, it is proved by calculating more than 6000 positions of background star distributed in an area about twice larger than the Airy disk in diameter.
