For active phasing of large segmented primary mirrors with thin, actively shaped controlled segments, we propose the use of a new, random phase-shift, dual wavelength, interferometric technique. We have considered a Michelson- type interferometer with diode lasers placed in the center of curvature of the primary, but another version employing a Mach-Zehnder interferometer with a pinhole in one arm placed in the telescope focal plane and using real or artificial star sources may also be considered. Results from a demonstration experiment are presented and discussed.
