    first class prize of science & technology progress award of Jiangsu province in 2005second class prize of national science & technology progress award in 2006


     The experiment facility includes: 1):one of submirrors of Schmidt corrector plate MA and its active supporting system;
    2): one of submirrors of spherical primary mirror MB and its supporting system;
    3):alt-azimuth mount;
    4):focal plane and Shack-Hartmann wavefront detector。
        Two submirror has same diagonal of 1100mm,but different thickness of 25mm and 75mm respectively。The experiment facility is actually small LAMOST with aperture of 1m and optical axis length of 40m。Outdoor active optics experiment which can simulate different submirror and track celestial body in real time has been conducted by the experiment facility。
      In 2002,close-loop outdoor active optics for thin mirror experiment succeed (80% encircled energy within 0.5 arcseconds )。In 2004,open-loop experiment succeed (80% encircled energy within 1.5 arcseconds )。
