Toward Strehl-Optimizing Adaptive Optics Controllers
Donald T. Gavel,Donald M. Wiberg +1 more
TL;DR: A general framework for a dynamic controller/reconstructor design where the goal is to maximize mean closed-loop Strehl ratio over time using all previous data and exploiting the spatial-temporal statistics of the Kolmogorov turbulence and measurement noise is presented.

Centroid gain compensation in Shack-Hartmann adaptive optics systems with natural or laser guide star
Jean-Pierre Véran,Glen Herriot +1 more
TL;DR: This work presents a novel method to estimate and compensate WFS gains of each subaperture individually in real time for both natural and laser guide stars.

Adaptive optics control strategies for extremely large telescopes
TL;DR: In this paper, scaling laws and strawman error budgets for AO systems on extremely large telescopes (ELTs) are presented and the implications for component technology and computational architecture are discussed.
Analysis of Non-Uniform Gain for Control of a Deformable Mirror in an Adaptive-Optics System
TL;DR: The non-uniform gain experiment (NUGE) as mentioned in this paper was conducted at the Starfire Optical Range (SOR), AFRL, Kirtland AFB to evaluate the performance of the servo-loop controller of a deformable mirror.
Journal ArticleDOI
Theory and operation of a robust controller for a compact adaptive optics system
TL;DR: The design and operation of a high-speed adaptive optics system using a robust H ∞ controller is described, which can be used in almost any application with minimal modifications and can be set up and operated by a minimally trained operator.

Interference model for back-focal-plane displacement detection in optical tweezers.
F. Gittes,Christoph F. Schmidt +1 more
TL;DR: A model is provided for the essential mechanism of intensity shifts as first-order far-field interference between the outgoing laser beam and scattered light from the trapped particle, where the latter is phase advanced owing to the Gouy phase anomaly.

Minimum Lp-norm two-dimensional phase unwrapping
TL;DR: In this paper, the minimum Lp-norm solution is obtained by embedding the transform-based methods for unweighted and weighted least squares within a simple iterative structure, and the data-dependent weights are generated within the algorithm and need not be supplied explicitly by the user.
