Abstract

The two Large Binocular Telescope (LBT) Adaptive Secondary Mirror (ASM) units operate as a part of the telescope and are fully integrated with it, this integration requires a significant interaction with the other telescope sub-systems and instruments for both seeing limited and AO operations. In this paper we will discuss some of the ASM functionalities developed for the AO operation and their control implementation. These include the optical aberration management and control and the compensation of instrument non-common path aberrations and the application of specific shapes. Finally, we will also discuss a new mirror control mode, named mixed-mode control, that allows us to continue using actuators that are showing stability issues while maintaining similar performances, until the next maintenance time.
