The path to agile extreme adaptive optics at the Large Binocular Telescope Observatory

The Large Binocular Telescope Observatory (LBTO) has pioneered major advancements in Adaptive Optics (AO) technologies, including the development of the adaptive secondary mirror (ASM), the pyramid wavefront sensor (PWFS), and ground-layer AO (GLAO) utilizing Rayleigh lasers for 8- to 10-meter class telescopes. We pres...

Non-invasive optical gain estimation in pyramid wavefront sensors from telemetry using machine learning

A machine-learning approach to forecast Gopt non-invasively from synchronized AO telemetry, which provides an operational path for using telemetry-based optical-gain prediction as a smoothing, validation, or no-probe fallback layer in the real-time AO loop.
