Gemini Planet Imager Observational Calibrations III: Empirical Measurement Methods and Applications of High-Resolution Microlens PSFs
Patrick Ingraham, Jean-Baptiste Ruffio, Marshall D. Perrin +5
The newly commissioned Gemini Planet Imager (GPI) combines extreme adaptive optics, an advanced coronagraph, precision wavefront control and a lenslet-based integral field spectrog…
Characterization of the Atmospheric Dispersion Corrector of the Gemini Planet Imager
Pascale Hibon, Sandrine Thomas, Jennifer Dunn +18
An Atmospheric Dispersion Corrector (ADC) uses a double-prism arrangement to nullify the vertical chromatic dispersion introduced by the atmosphere at non-zero zenith distances. Th…
Beam shaping for laser-based adaptive optics in astronomy
Clémentine Béchet, Andrés Guesalaga, Benoit Neichel +5
The availability and performance of laser-based adaptive optics (AO) systems are strongly dependent on the power and quality of the laser beam before being projected to the sky. Fr…
