Results from the commissioning of the Gemini South Adaptive Optics Imager (GSAOI) at Gemini South Observatory
2012
We present the results from the commissioning of the Gemini South Adaptive Optics Imager (GSAOI). Capable
of delivering diffraction limited images in the near-infrared, over an 85′′
×85′′ square field-of-view, GSAOI was
designed for use with the Gemini Multi-Conjugate Adaptive Optics (GeMS) system in operation at the Gemini
South Observatory. The instrument focal plane, covered by an array of four HAWAII-2RG detectors, contains
4080×4080 pixels and has a plate scale of 0.02′′ – thus capitalizing on the superb image quality delivered by both
the all-refractive optical design of GSAOI and the Gemini South MCAO system. Here, we discuss our preliminary
findings from the GSAOI commissioning, concentrating on detector characterization, on-sky performance and
system throughput. Further specifics about the Gemini MCAO system can be found in other presentations at
this conference.
