GRAVITY+ Wavefront Sensors: High-Contrast, Laser Guide Star, Adaptive Optics systems for the VLTI
We present the Wavefront Sensor units of the Gravity Plus Adaptive Optics
(GPAO) system, which will equip all 8m class telescopes of the VLTI and is an
instrumental part of the GRAVITY+ project. It includes two modules for each
Wavefront Sensor unit: a Natural Guide Star sensor with high-order 40x40
Shack-Hartmann and a Laser Guide Star 30x30 sensor. The state-of-the-art AO
correction will considerably improve the performance for interferometry, in
particular high-contrast observations for NGS observations and all-sky coverage
with LGS, which will be implemented for the first time on VLTI instruments. In
the following, we give an overview of the Wavefront Sensor units system after
completion of their integration and characterization.
