中文摘要 | The support systems of primary mirrors usually consist of axial supports and lateral supports. The surface of an active thin mirror is maintained through actuators on back of the mirror. The axial and lateral supports are designed for a 1.2 m thin mirror with the aspect ratio of 24. The 36 axial supports are equally distributed on three rings and normalized radiuses are 0.275, 0.583 and 0.897 respectively. The numbers of axial supports for each ring are 6, 12 and 18 respectively. Three lateral support units are equally distributed at the outer edge of the mirror. The optimum surfaces are 2.7 nm and 12 nm RMS respectively when the mirror is mounted horizontally and vertically. It's also demonstrated that the active supports could correct most of manufacture errors. © 2012 SPIE. |
