TL;DR
MAORY is an adaptive optics module for the ELT that enables high-resolution near-infrared observations over a large field of view by real-time atmospheric turbulence correction using laser and natural guide stars.
Contribution
It introduces a multi-conjugate adaptive optics system for the ELT that integrates wavefront sensing and correction with multiple guide stars and deformable mirrors.
Findings
Provides high angular resolution in near-infrared observations.
Achieves large field of view (~1 arcmin^2) with real-time wavefront correction.
Integrates with telescope's adaptive optics system for improved performance.
Abstract
MAORY is the adaptive optics module for ELT providing two gravity invariant ports with the same optical quality for two different client instruments. It enable high angular resolution observations in the near infrared over a large field of view (~1 arcmin2 ) by real time compensation of the wavefront distortions due to atmospheric turbulence. Wavefront sensing is performed by laser and natural guide stars while the wavefront sensor compensation is performed by an adaptive deformable mirror in MAORY which works together with the telescope's adaptive and tip tilt mirrors M4 and M5 respectively.
