Abstract

Technion Israel Institute of Technology, Israel

The combination of several telescopes is appealing from the scientific standpoint due to the more efficient sampling of the spatial frequency plane. Among other basic requirements, the beams are to be brought and retained into a fixed phase relation, against atmospheric piston. The necessary phase measurements (and corrections) are basically linear with the number of telescopes. This suggests the possibility of a convenient modular approach based on current technology. Besides, fringe tracking may benefit from efficient beam combination schemes and technological innovations in detector and optical components for astronomy.
