The space coronagraph optical bench (SCoOB): 4. vacuum performance of a high contrast imaging testbed
Kyle Van Gorkom, Ewan S Douglas, Kian Milani +8
The Space Coronagraph Optical Bench (SCoOB) is a high-contrast imaging testbed built to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuum e…
Approaches to lowering the cost of large space telescopes
Ewan S Douglas, Greg Aldering, Greg W. Allan +26
New development approaches, including launch vehicles and advances in sensors, computing, and software, have lowered the cost of entry into space, and have enabled a revolution in…
Microfabricated pinholes for high contrast imaging testbeds
Emory L. Jenkins, Kyle Van Gorkom, Kevin Derby +2
In order to reach contrast ratios of and beyond, coronagraph testbeds need source optics that reliably emulate nearly-point-like starlight, with microfabricated pinholes…
Status and performance of the Gemini Planet Imager adaptive optics system
Vanessa P. Bailey, Lisa A. Poyneer, Bruce A. Macintosh +14
The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science d…
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…
Gemini Planet Imager Observational Calibrations V: Astrometry and Distortion
Quinn M. Konopacky, Sandrine J. Thomas, Bruce A. Macintosh +24
We present the results of both laboratory and on sky astrometric characterization of the Gemini Planet Imager (GPI). This characterization includes measurement of the pixel scale o…
