In this paper we report on measurements of atmospheric turbulence effects arising from water air interaction. The aim of this study is to aid in the design of a free-space optical relay system to facilitate longer line-of-sight distances between rela

Phase singularities have been shown to cause one of the major problems for adaptive optics (AO) systems which attempt to correct for distortion caused by the atmosphere in line of sight free space optical communications over mid-to-long range horizon

We present results of adaptive optics compensation at the receiver of a 3km optical link using a beacon laser operating at 635nm. The laser is transmitted from the roof of a seven-storey building over a near horizontal path towards a 127 mm optical r

Branch points have been shown to cause problems for adaptive optics (AO) systems which attempt to correct for atmospheric distortion over mid-to-long range horizontal paths. Where branch points (or singularities) occur, the phase of the optical wavef

The Applied Optics group at the National University of Ireland, Galway, is engaged in research into various aspects of the application of adaptive optics to both ocular and atmospheric wavefront correction. A large number of commercially available de

We present the optical design of a laboratory demonstrator for a low-order adaptive optics system with possible application to improving the performance of a free-space optical communication system. The initial design includes a Shack-Hartmann wavefr

When light propagates through the atmosphere the fluctuating refractive index caused by temperature gradients, humidity fluctuations and the wind mixing of air cause the phase of the optical field to be corrupted. In strong turbulence, over horizonta

The main applications of adaptive optics are the correction of the effects of atmospheric turbulence on ground-based telescopes and the correction of ocular aberrations in retinal imaging and visual simulation. The requirements for the wavefront corr
