Abstract

The method for phasing segmented mirrors by forming a reference (spherical or aspherical) surface by means of a system of small mirrors and an common-path interferometer has been developed. The method is being applied for the accurate comparison of curvature radii during shaping large mirrors surfaces (error approximately 10^-4 per cent).
