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

Adaptive Optics for Extremely Large Telescopes [PDF]
Journal of Astronomical Instrumentation, 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 in laser processing [PDF]
Light: Science & Applications, 2019 AbstractAdaptive optics are becoming a valuable tool for laser processing, providing enhanced functionality and flexibility for a range of systems. Using a single adaptive element, it is possible to correct for aberrations introduced when focusing inside the workpiece, tailor the focal intensity distribution for the particular fabrication task and/or ...

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 ...

Adaptive optics for optical microscopy [Invited]. [PDF]
Biomed Opt Express, 2023 Optical microscopy is widely used to visualize fine structures. When applied to bioimaging, its performance is often degraded by sample-induced aberrations. In recent years, adaptive optics (AO), originally developed to correct for atmosphere-associated aberrations, has been applied to a wide range of microscopy modalities, enabling high- or super ...

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 ...
