OVMS-plus at the LBT: disturbance compensation simplified

Böhm, Michael, Pott, Jörg-Uwe, Borelli, José, Hinz, Phil, Defrère, Denis, Downey, Elwood, Hill, John, Summers, Kellee, Conrad, Al, Kürster, Martin, Herbst, Tom, Sawodny, Oliver 27 July 2016 (has links)
In this paper we will briefly revisit the optical vibration measurement system (OVMS) at the Large Binocular Telescope (LBT) and how these values are used for disturbance compensation and particularly for the LBT Interferometer (LBTI) and the LBT Interferometric Camera for Near-Infrared and Visible Adaptive Interferometry for Astronomy (LINC-NIRVANA). We present the now centralized software architecture, called OVMS+, on which our approach is based and illustrate several challenges faced during the implementation phase. Finally, we will present measurement results from LBTI proving the effectiveness of the approach and the ability to compensate for a large fraction of the telescope induced vibrations.
