Synthetic aperture co-phasing and co-alignment using an external reference source

Autor: Nicolas Loix, Jean-Hervé Lecat, Jean-Christophe Bolsee, Stéphane Roose

Publikováno v: International Conference on Space Optics — ICSO 2006.

A breadboard set-up has demonstrated a concept of cophasing and co-alignment based on an external reference source for synthetic aperture telescopes applications. These types of systems can be extremely valuable in order to perform coarse re-alignmen
