Adaptive Optics pre-compensated laser uplink to LEO and GEO.
Optics Express, 2021 We present the results from a Monte Carlo computer simulation of adaptive optics (AO) pre-compensated laser uplink propagation through the Earth's atmospheric turbulence from the ground to orbiting satellites.

MICADO: the E-ELT adaptive optics imaging camera [PDF]
Astronomical Telescopes + Instrumentation, 2010 MICADO is the adaptive optics imaging camera for the E-ELT. It has been designed and optimised to be mounted to the LGS-MCAO system MAORY, and will provide diffraction limited imaging over a wide (~1 arcmin) field of view.

Wavefront sensor-less adaptive optics using deep reinforcement learning.
Biomedical Optics Express, 2021 Image degradation due to wavefront aberrations can be corrected with adaptive optics (AO). In a typical AO configuration, the aberrations are measured directly using a Shack-Hartmann wavefront sensor and corrected with a deformable mirror in order to ...

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 ...

An adaptive optics module for deep tissue multiphoton imaging in vivo
Nature Methods, 2020 Understanding complex biological systems requires visualizing structures and processes deep within living organisms. We developed a compact adaptive optics module and incorporated it into two- and three-photon fluorescence microscopes, to measure and ...
