1.5.1.3 Next-generation interferometric infrastructure
The proceedings of the first workshop on next-generation interferometers, which had taken
place in Liège in 2004, appeared in print (“Science cases for Next Generation Optical/Infrared
Interferometric Facilities”, edited by J. Surdej, D. Caro, & A. Detal). The second study group
meeting took place on 04 to 08 July 2005 in Liège, in connection with the JENAM
conference. Building on the discussions of the science case for a next generation
interferometric facility, which had taken place in 2004, the 2005 meeting was devoted to the
identification of the most important technical issues. In total, some 50 participants were
actively involved during the Liège workshop. The workshop consisted of general
presentations summarizing concepts for future interferometric facilities and specific
technology needs. Contributed talks and posters were part of the programme. The main topics
discussed during the Liège workshop were:
- Perspectives for next generation ground- and space-based interferometers (O. Absil & D.
Mawet)
- Complementarity between space and ground-based interferometry (V. Coudé du Foresto
& S. Ridgway)
- Scientific requirements for space interferometric missions (M. Fridlund)
- A high-level technical overview of prototype and first-generation optical arrays (D.
Buscher)
- Cophasing and Fringe Tracking for future interferometers (M. Gai, D. Bonino, L.
Corcione, D. Gardiol, M.G. Lattanzi, D. Loreggia, G. Massone, S. Menardi, E. Ribak)
- Long baseline beam transport (G. Perrin)
- Concept of a pupil densification assembly using optical fibers (F. Patru, D. Mourard, O.
Lardière, A. Spang, J.M. Clausse, P. Antonelli, Y. Bresson, S. Lagarde)
- Single mode beam combination for interferometry (P. Kern)
- Algol-CPNG: The new generation photon counting cameras for visible interferometry (A.
Blazit, E. Thiébaut, F. Vakili, L. Abe, A. Spang, J.-M. Clausse, D. Mourard, X. Rondeau)
- Arrays with a wide field of view combination (A. Quirrenbach)
- Reconfiguration of 8m class telescopes (M. Kraus)
- Synergies between interfacing a future generation interferometer and ELTs (F.
Delplancke)
- Using interferometry to achieve high dynamic range imaging (S. Lacour & G. Perrin)
- The Large Binocular Telescope Model Extrapolated to ELTs (T. Herbst)
- Future optical very long baseline interferometers : the OVLA model – a well-populated
array (F. Vakili)
- Arrays without delay lines (V. Borkowski)
- Direct imaging: the natural choice for cophased interferometry (F. Martinache & O.
Lardiere)
- Site considerations for the next generation of optical arrrays: Mid-latitude sites versus
Antarctica (M. Sarazin)
- Perspective of Interferometry in Antarctica (B. Lopez, F.X. Schmider, F. Vakili, E.
Aristidi)
- AT telescopes at Dome C (O. Pirnay)
- Aladdin on the road to Darwin (V. Coudé du Foresto)
- EC proposal for FP7 and research infrastructures in astronomy (P. Moschopoulos)
- General conclusions (A. Quirrenbach)
