Abstract

The Gemini Planet Imager (GPI) is a facility extreme-AO high-contrast instrument– optimized solely for study of faint companions–on the Gemini telescope. It combines a high- order MEMS AO system (1493 active actuators), an apodized pupil Lyot coronagraph, a high- accuracy IR post-coronagraph wavefront sensor, and a near-infrared integral field spectrograph. GPI incorporates several other novel features such as ultra-high quality optics, a spatially-filtered wavefront sensor, and new calibration techniques. GPI had first light in ...
