Adaptive Optics for Astronomy [PDF]
Annual Review of Astronomy and Astrophysics, 2012 Adaptive Optics is a prime example of how progress in observational astronomy can be driven by technological developments. At many observatories it is now considered to be part of a standard instrumentation suite, enabling ground-based telescopes to reach the diffraction limit and thus providing spatial resolution superior to that achievable from space

PASSATA - Object oriented numerical simulation software for adaptive optics [PDF]
Proc. SPIE Vol. 9909 (2016), 2016 We present the last version of the PyrAmid Simulator Software for Adaptive opTics Arcetri (PASSATA), an IDL and CUDA based object oriented software developed in the Adaptive Optics group of the Arcetri observatory for Monte-Carlo end-to-end adaptive optics simulations.

Adaptive Optics for Extremely Large Telescopes [PDF]
, 2018 Adaptive Optics has become a key technology for the largest ground-based telescopes currently under or close to begin of construction. Adaptive optics is an indispensable component and has basically only one task, that is to operate the telescope at its maximum angular resolution, without optical degradations resulting from atmospheric seeing. Based on

Adaptive Optics Ophthalmoscopy [PDF]
Journal of Refractive Surgery, 2000 ABSTRACT Retinal images in the human eye are normally degraded because we are forced to use the optical system of the human eye- which is fraught with aberrations - as the objective lens. The recent application of adaptive optics technology to measure and compensate for these aberrations has produced retinal images in human eyes with ...

Adaptive Optics Simulations for Siding Spring [PDF]
, 2012 Using an observational derived model optical turbulence profile (model-OTP) we have investigated the performance of Adaptive Optics (AO) at Siding Spring Observatory (SSO), Australia. The simulations cover the performance for AO techniques of single conjugate adaptive optics (SCAO), multi-conjugate adaptive optics (MCAO) and ground-layer adaptive ...

eLight, 2023 AbstractAdaptive optics normally concerns the feedback correction of phase aberrations. Such correction has been of benefit in various optical systems, with applications ranging in scale from astronomical telescopes to super-resolution microscopes. Here we extend this powerful tool into the vectorial domain, encompassing higher-dimensional feedback ...

Living Reviews in Solar Physics, 2011 Adaptive optics (AO) has become an indispensable tool at ground-based solar telescopes. AO enables the ground-based observer to overcome the adverse effects of atmospheric seeing and obtain diffraction limited observations. Over the last decade adaptive optics systems have been deployed at major ground-based solar telescopes and revitalized ground ...

Optical-component-only adaptive optics
Optics Letters, 2021 This Letter introduces a technique for performing binary adaptive optics, which is carried out by optical components only, without the help of any electronic or optoelectronic device. In this technique, the interferogram produced by a point diffraction interferometer modulates a light-driven crystal. The modulated light-driven crystal may produce pupil-

Optofluidic adaptive optics in multi-photon microscopy [PDF]
Biomedical Optics Express, Vol. 14, Issue 4, pp. 1562-1578 (2023), 2022 Adaptive optics in combination with multi-photon techniques is a powerful approach to image deep into a specimen. Remarkably, virtually all adaptive optics schemes today rely on wavefront modulators which are reflective, diffractive, or both. This, however, can pose a severe limitation for applications.

IEEE Photonics Journal, 2022 Correction performance of an adaptive optics (AO) system is severely limited by its system latency under high temporal frequency distortions. Wavefront prediction methods has been proven to be an effective way to compensate system delay.
