Tilt anisoplanatism in laser-guide-star-based multiconjugate adaptive optics Reconstruction of the long exposure point spread function from control loop data

Abstract

A method is presented for estimating the long exposure point spread function (PSF) degradation due to tilt anisoplanatism in a laser-guide-star-based multiconjugate adaptive optics systems from control loop data. The algorithm is tested in numerical Monte Carlo simulations of the separately driven low-order null-mode system, and is shown to be robust and… (More)
