ABSTRACT:
In a reflecting mirror, a plurality of segmented mirrors are grouped into a plurality of groups of a cluster, and are supported by a plurality of sub mirror cells. The plurality of sub mirror cells are supported by a mirror cell, and all the segmented mirrors are supported by the mirror cell. A reference cell is supported by a plurality of force support mechanisms disposed in the mirror cell with the reference cell being nearly in a weightlessness state. Projections and depressions are prevented from occurring in an axial direction of the reflecting mirror due to a self weight deformation, and the reference cell can be used as a reference surface for control of the positions of the plurality of segmented mirrors and those of the plurality of cluster mirrors in the axial direction of the reflecting mirror.
