Abstract

The Multi-conjugate Adaptive Techniques Test Optics (MATTO) is a comprehensive adaptive optics (AO) test bench in development at the INAF-Astronomical Observatory of Padova. Actining as a wide field AO facility, MATTO aims to host future proof-of-concept tests of new methods and serves as a versatile platform for researching and refining Multi-Conjugate Adaptive Optics (MCAO) techniques across diverse conditions. MATTO features independently configurable modules: the reference source module generates atmosphere-perturbed beams, simulating both natural and artificial references with various spectra and asterisms. A telescope simulator module replicates the lower atmosphere's beam geometry by combining light from these references. The MCAO correction module, equipped with three large deformable mirrors, enables the implementation of various compensation schemes with variable conjugation altitudes. Additionally, a sensing module equipped with spatial light modulators (SLM), allows to replicate a range of wavefront sensors, offering flexibility in the positioning of the sensing elements. MATTO emerges as a flexible and essential tool for advancing MCAO research and development.
