GSAOI
Overview
The Gemini South Adaptive Optics Imager (GSAOI) is a near-infrared adaptive optic camera that will be used with the Gemini Multi-conjugate Adaptive Optics System (GeMS) on Gemini South. GSAOI was built by the Research School of Astronomy and Astrophysics (RSAA) of The Australian National University.
GSAOI provides diffraction limited images in the 0.9 - 2.4 μm wavelength range. The GSAOI imager detector is formed by 2 x 2 mosaic Rockwell HAWAII-2RG 2048 x 2048 arrays. Located at the f/32 GeMS output focus, GSAOI records images in a 85" x 85" field-of-view with a imaging scale of 0.02"/pixel and a gap between the arrays of ~ 2mm. In the adaptive optic sense, GSAOI is a wide-field imaging system with a 4080 x 4080 pixel detector format.
The Instrument Scientist for GSAOI is Rodrigo Carrasco. Gemini staff who also support GSAOI are Claudia Winge, Peter Pessev, Ariel Lopez and Andrew Serio
