Poyneer,Anand Sivaramakrishnan,Anand Sivaramakrishnan,Rémi Soummer,Rémi Soummer,Jean-Pierre Véran +24 more
TL;DR: The Gemini Planet Imager (GPI) as discussed by the authors is a system that combines a high-order/high-speed adaptive optics system to control wavefront errors from the Earth's atmosphere, ultrasmooth optics, a precision infrared interferometer to measure and correct systematic errors, and a integral field spectrograph/polarimeter to image and characterize target planetary systems.
Detecting and characterizing exoplanets with a 1.4-m space telescope: The Pupil mapping Exoplanet Coronagraphic Observer (PECO)
