Abstract
A cophasing system architecture has been derived for an imaging multi-aperture optical space interferometer. This system is based on cophasing on a guide star. Breadboarding and testing of the main part of the system, with emphasis on the critical items (delay line, cophasing interferometer, Optical Path Difference (OPD retrieval methods), has provided an evaluation of the expected performance. This paper describes the reference interferometry mission used for the study, the overall OPD stabilization concept, the cophasing system and associated OPD restitution algorithms, and the first test results.
