A computationally efficient autoregressive method for generating phase screens with frozen flow and turbulence in optical simulations
Sriakr Srinath, Lisa A. Poyneer, Alexander R. Rudy +1
We present a sample-based, autoregressive (AR) method for the generation and time evolution of atmospheric phase screens that is computationally efficient and uses a single paramet…
Pictoris' inner disk in polarized light and new orbital parameters for Pictoris b
Maxwell A. Millar-Blanchaer, James R. Graham, Laurent Pueyo +54
We present -band observations of Pic with the Gemini Planet Imager's (GPI's) polarimetry mode that reveal the debris disk between ~0.3" (~6 AU) and ~1.7" (~33 AU), while sim…
Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager
B. Macintosh, J. R. Graham, T. Barman +85
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation mechani…
A laboratory demonstration of an LQG technique for correcting frozen flow turbulence in adaptive optics systems
Alexander Rudy, Lisa Poyneer, Srikar Srinath +2
We present the laboratory verification of a method for re- moving the effects of frozen-flow atmospheric turbulence using a Linear Quadratic Gaussian (LQG) controller, also known a…
