TL;DR: The Gemini Planet Imager (GPI) as discussed by the authors is a system for direct imaging of the planets themselves, which can achieve contrast levels of 10-7 to 10-8, sufficient to detect warm self-luminous Jovian planets.
Proceedings ArticleDOI
Exoplanet imaging with LOCI processing: photometry and astrometry with the new SOSIE pipeline
TL;DR: In this paper, the authors present several biases that are uncovered while analyzing data on the HR8799 planetary system and how they have modified their analysis pipeline to calibrate or remove these effects so that high accuracy photometry and photometry is achievable.
Journal ArticleDOI
Analytical modeling of adaptive optics: foundations of the phase spatial power spectrum approach.
TL;DR: This paper presents the foundations of a modeling method for the AO optical transfer function, based on an analytical description of the residual phase spatial power spectrum, in an IDL-based code, and comparison with end-to-end simulations demonstrates the validity of this approach.
Journal ArticleDOI
Fourier transform wavefront control with adaptive prediction of the atmosphere
TL;DR: Predictive Fourier control is a temporal power spectral density-based adaptive method for adaptive optics that predicts the atmosphere under the assumption of frozen flow and improves atmospheric rejection, leading to significant improvements in system performance.
Journal ArticleDOI
Optimal modal Fourier-transform wavefront control
Lisa Poyneer,Jean-Pierre Véran +1 more
TL;DR: The modal basis is the real Fourier basis, which allows direct control of specific regions of the point-spread function and is computationally efficient enough to be implemented with off-the-shelf technology for a 2.5 kHz, 64 x 64 adaptive optics system.
