摘　　要：光干涉仪采用带有地平式定天镜的集光装置,是能给出足够大天空覆盖的最佳配置形式。同时,对天体两个给定的坐标值,按方位列表给出定天镜法线的位置、速度和加速度的值。为光干涉仪样机和将来发展实用型光干涉仪的方案及其伺服控制提供依据。In this paper we discuss advantages of Alt-Azi mounted siderostats for an optical interferometer, and suggest an optimum optical configuration of siderostat-telescope, which could cover a large field of sky. The values of positions, speeds and accelerations for the normal of a siderostat were calculated for stars located at different zenith and azimuth.
