We theoretically study the potential of adaptive optics (AO) to protect entanglement of high-dimensional photonic orbital-angular-momentum (OAM) states against turbulence-induced phase distortions. We demonstrate that AO is able to reduce crosstalk a

Endoscopic Microscopy XV.
A miniature endomicroscope is presented that combines a large field-of-view (up to 1.7 mm) for OCT-imaging and a high-resolution mode with 360 μm field-of-view (NA = 0.5) for multi-photon fluorescence or OCT imaging. The 4.7x magnification variation

The measured fiber coupling efficiency (FCE) in atmospheric laser communication is not fully explored. We experimentally study the FCE for tip-tilt aberrations. Finally, we explain the FCE with the tip-tilt phase response.

Though long anticipated, adaptive optical (AO) pre-compensation is now experiencing a surge in interest thanks to technological advances and the identification of a real-world application with the advent of satellite laser communication as a viable a

In the development of laser communication networks, atmospheric turbulence remains an obstacle in the efficiency optimisation of bidirectional optical links. Post-compensation of the downlink signal through adaptive optics (AO) has been verified as a

Adaptive optical pre-compensation is seen as crucial for free-space laser communication in order to overcome the influence of atmospheric turbulence, particularly with respect to Earth-to-GEO feederlinks. This paper presents an experimental investiga

This paper describes an opto-mechanical concept of a deformable metal mirror membrane, which can shift the focus position over a large range by use of a single actuator. The core element of the mirror is a diamond turned tulip-shaped membrane, the de

A deformable mirror (DM) is a device that aims to compensate laser-induced mirror deformation and thermal lensing in the optical system. The mounting of membrane based DM with screen-printed actuators is crucial, as stress may deform the membrane and

The next generation of large monolithic mirror space telescopes will use aberration correction to ensure resolution performance is maintained throughout their mission. This is due to the use of ever thinner and lighter primary mirrors, which are susc

Manufacturing telescopes with 4, 8 or 16 meter apertures is the most effective way to gather the light of faint exoplanets or look back towards the Big Bang. However, ultra-high optical quality large mirrors drastically increase the mass of such inst
