摘要：

ARGOS is the ground-layer adaptive optics system for the Large Binocular Telescope. In order to perform its wide-field correction, ARGOS uses three laser guide stars which sample the atmospheric turbulence. To perform the correction, ARGOS has at disposal three different wavefront sensing measurements : its three laser guide stars, a NGS tip-tilt, and a third wavefront sensor. We present the wavefront sensing architecture and its individual components, in particular : the finalized ARGOS PNCCD camera detecting the 3 laser guide stars at 1kHz, high quantum efficiency and 4e(-) noise; the ARGOS tip-tilt sensor based on a quad-cell avalanche photo-diodes; and the ARGOS wavefront computer. Being in the middle of the commissioning, we present the first wavefront sensing configurations and operations performed at LBT, and discuss further improvements in the measurements of the 3 laser guide star slopes as detected by the PNCCD.
