Abstract

The active optics system of the VLT Survey Telescope (VST) adopts a positioning system for the secondary mirror, a system to support and modify the shape of the 2.6-m primary mirror, and a Shack-Hartmann wavefront sensor. This paper describes the concepts of the VST active optics and the commissioning of the whole system on the ESO's Paranal Observatory.
