Synergies between a Future Generation Interferometer and Extremely Large Telescopes
Proceedings of the European Interferometry Initiative Workshop organized in the context of the 20005 Joint European and National Astronomy Meeting "Distant Worlds"?
Abstract
The potential synergies between Extremely Large Telescopes (ELT) and New Generation Optical and Infra-red Interferometers (NGOI) are investigated both on the scientific field and on the technical point of view. ELTs would provide full u-v coverage and imaging capabilities up to baselines of several tens of meters on very faint objects but would be limited mainly by the performance and artifacts left over from the segmented technology and adaptive optics. NGOIs with very long baselines (up to several kilometers) would give access to even smaller details with much better mastered and easier to calibrate artifacts but only on relatively bright objects. So ELTs and NGOIs are more complementary than concurrent. Synergies on the technologies to be developed for both projects as well as the different requirements and constraints in terms of site choice are also highlighted.
