The ambition of the project MOAI (MethOds And Instrumentation for laser guide star wavefront sensing) is to evaluate the feasibility of tip-tilt correction with Polychromatic Laser Guide Stars, and investigate and propose innovative concepts for LGS Wave-Front Sensing.

Adaptive optics (AO) together with sodium laser guide stars (LGS) have revolutionized astronomical observations in the last decades.
The new generation of Extremely Large Telescopes (ELTs) will require and integrate AO-assisted observations to comply with their scientific programs, however, extrapolating the current AO technology to the dimensions of the ELTs encounters technological barriers (large, sensitive, and fast detectors) and fundamental limitations derived from the geometry and properties of LGS (spot elongation and tip-tilt indetermination). Therefore, the aim of the MOAI project is to develop MethOds And Instrumentation for laser guide star wavefront sensing (LGSWFS), in view of the challenges imposed by the future ELTs. The goals of MOAI are :

i) Evaluate the feasibility of LGS tip-tilt correction using the polychromatic laser guide star concept.
ii) Investigate and propose an innovative concept of LGSWFS for ELTs.
iii) Demonstrate a new LGSWFS technology.

The project will be carried out at the Laboratoire d’Astrophysique de Marseille (LAM) in strong collaboration with researchers in Europe and North America.

Achieving the objectives of MOAI will considerably extend the capabilities of AO-assisted observations, which will constitute a significant contribution to enable new astrophysical discoveries in the upcoming era of ELTs.
