Many of the proposed science cases for extremely large telescopes (ELT) are only possible because of the unprecedented sensitivity and spatial resolution due to advanced, e.g. tomographic and multi conjugate, adaptive optic (AO) systems. Current AO s

Direct imaging is a powerful tool for exoplanet atmosphere characterization. High performance of these techniques requires extreme wavefront correction for ground-based instruments as well as space projects. Wavefront sensors are usually physically s

Present and future adaptive optics systems aim for the correction of the atmospheric turbulence over a large field of view combined with large sky coverage. Thus they use multiple laser beacons on sky. Still usually a guide star for correction of the

Raven is a MOAO demonstrator that will be mounted on the Nasmyth platform of the Subaru telescope and is intended to serve as a pathfinder for future ELT MOAO instruments.We present the Raven wavefront error budget that was used to define the AO arch

The next generation of adaptive optics (AO) systems require tomographic techniques in order to correct for atmospheric turbulence along lines of sight separated from the guide stars. Multi-object adaptive optics (MOAO) is one such technique. Here, we

The direct exoplanet imaging field will strongly benefit from the higher angular resolution achieved by next generation 30+m telescopes. To fully take advantage of these new facilities, one of the biggest challenges that ground-based adaptive optics

This paper presents a linear quadratic Gaussian (LQG) command based design approach for the con- trol of an astronomical adaptive optics system. In this framework, the control uses the state-feedback of the atmospheric distortion wavefront estimate.
