The Gemini South Adaptive Optics Imager (GSAOI) is a near-infrared adaptive optics camera 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 near-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 science staff who also support GSAOI is Joy Chavez.
