Abstract

The development of the interferometric near-infrared camera LINC/NIRVANA for the Large Binocular Telescope (LBT) is an international collaboration of the Max-Planck-Institute for Astronomy in Heidelberg (PI institute), the Osservatorio Astrofisico di Arcetri and the I. Physikalische Institut of the University of Cologne. LINC/NIRVANA will allow for interferometric imaging in the near-infrared JHK bands with high angular resolution (about 9, 12 & 17 mas at respective wavelengths) over a wide field of view (FOV ≈ 100 arcsec2). This FOV is sufficiently large to observe the entire central stellar cluster of the Galactic Center with one single exposure [Rubilar 2001], a unique possibility that makes LINC/NIRVANA the detector system of choice for scientific investigations of respective stellar populations and dynamics. In this article we summarise the implications of the Fizeau-type optical layout of the LBT for interferometric imaging and present the principle of operation and current design concept of the LINC/NIRVANA camera.
