Proliferation of space debris presents an imminent threat to all space assets. The problem is especially severe for the geostationary band of orbits (GEO) because the GEO objects never leave their orbit and, at the same time, are difficult to observe

Turbulence estimation in ground based telescopes as part of the Adaptive Optics (AO) control loop is inherently high-complexity. Even in smaller telescopes such as the EOS 1.8m telescope at Mt Stromlo Observatory, Canberra, closed-loop control system

The adaptive optics (AO) systems with multiple laser guide stars (LGSs) may significantly benefit in terms of hardware simplification from merging several LGS optical channels into one with a single wavefront sensor. As Shack-Hartmann sensors typical

We describe a complexity reduction approach intended to solve the tomographic alignment problem for the Thirty Meter Telescope by means of its alignment and phasing system (APS) with little loss of information. This approach is computationally effici

The Alignment and Phasing System (APS) is one of the key parts of the Thirty Meter Telescope (TMT) active optics system, with the responsibility for evaluating and correcting the pre-adaptive optics wavefront delivered by the telescope. APS is a high
