note = "Funding Information: Multi-Object Adaptive Optics (MOAO)1 provides AO compensation simultaneously in multiple directions on the sky. The technique involves using a deformable mirror (DM) for each science channel, driven by commands generated from muoltiple wave front sensors (WFS), and can elegantly overcome the limitations of anisoplanatism and DM projection error terms. MOAO systems of the future will deliver diffraction-limited images over a large field of regard (FoR). On Extremely Large Telescopes (ELTs) with multiple Laser Guide Stars (LGSs), a MOAO-fed instrument with at least 20 science pick-offs spread over a FoR of at least 5 arcminutes should deliver 50% ensquared energy (EE) within a 50 milli-arcsecond spaxel in H-band over 90% of the sky2,3. With this potentially impressive performance and large multiplexing advantage, MOAO instruments should be work-horse instruments on ELTs. However, before serious design work can proceed on these future ELT instruments, the technical risks associated with this novel AO concept must be mitigated. The community has responded with a series of increasingly complex on-sky demonstrators, most notably, Canary4 and Raven5, and now the Gemini Infrar-Red Multiple Object Spectrograph (GIRMOS) as a facility-class instrument for Gemini. GIRMOS is a Canadian instrument recently funded by the Canada Foundation for Innovation (CFI) and provincial governments.
