Abstract
LINC-NIRVANA is an infrared camera that will work in Fizeau interferometric way at the Large Binocular Telescope (LBT). It will take advantage of a field corrected from two MCAO systems, one for each arm, based on the Layer Oriented Technique and using solely Natural Guide Stars. For each arm, there will be two wavefront sensors, one conjugated to the Ground and one conjugated to a selectable altitude, ranging from 4 to 15 Km. They will explore different fields of view for the wavefront sensing operations, accordingly to the Multiple Field of View concept, and particularly the inner 2 arcminutes FoV will be used to select the references for the high layer wavefront sensor while the ground one will explore a wider anular field, going from 2 to 6 arcminutes in diameter. The wavefront sensors are under INAF responsibility, and their construction is ongoing in different italian observatories. Here we report on progress, and particularly on the test ongoing in Padova observatory on the Ground Layer Wavefront Sensor.
