TL;DR: The MAORY as discussed by the authors is a post-focal adaptive optics module that forms part of the first light instrument suite for the ELT, which relay the light beam from the focal plane to the client instrument while compensating the effects of the atmospheric turbulence and other disturbances affecting the wavefront from the scientific sources of interest.
Proceedings ArticleDOI
Imaging beyond the fringe: an update on the LINC-NIRVANA Fizeau interferometer for the LBT
TL;DR: The LINC-NIRVANA as mentioned in this paper is a Fizeau-mode imaging interferometer for the Large Binocular Telescope (LBT) that uses visible wavelength radiation for wavefront control, and the near-infrared bands for science and fringe tracking.
Proceedings ArticleDOI
Is there need of any modulation in the pyramid wavefront sensor
Joana Buechler Costa,Roberto Ragazzoni,Adriano Ghedina,Marcel Carbillet,Christophe Verinaud,Markus Feldt,Simone Esposito,Elena Puga,Jacopo Farinato +8 more
TL;DR: A preliminary study showing that this sort of 'natural' modulation could be, at least under certain conditions, enough to reach comparable results with respect to dynamical modulation during correction, hence rising the question of the need of a modulation in the realization of the pyramid wavefront sensor.
Proceedings ArticleDOI
The LINC-NIRVANA interferometric imager for the Large Binocular Telescope
TL;DR: LINC-NIRVANA as discussed by the authors is a 1-2.5 micron interferometric imaging instrument for the Large Binocular Telescope (LBT) with a field of view of ten arcseconds on a single HAWAII-2 detector array.
