Estimation of the lateral mis-registrations of the GRAVITY<sub>+</sub> adaptive optics system
Estimation of the lateral mis-registrations of the GRAVITY<sub>+</sub> adaptive optics system
Context. The GRAVITY+ upgrade implies a complete renewal of its adaptive optics (AO) systems. Its complex design, featuring moving components between the deformable mirrors and the wavefront sensors, requires the monitoring and auto-calibrating of the lateral mis-registrations of the system while in operation. Aims. For preset and target acquisition, large …
