Communications and Observations through Atmospheric Turbulence
A multidisciplinary workshop to address the biggest challenges in free-space optical propagation from astronomy to laser communications.
29th – 31st March 2023, Durham, UK
The conference will take place in the Calman Learning Centre on the University Science site:
- Modelling, measurement & forecasting
- Impact of turbulence
- Adaptive optics & mitigation strategies
- Novel concepts and applications
- Experimental demonstrations
Some presentations with permission from the author are available to download here. Please use the programme above to identify titles and authors.
In a large variety of fields, the development of ever more demanding optical systems now requires a thorough understanding of the impact of atmospheric turbulence together with the development of dedicated mitigation strategies. Originally driven by astronomy, these issues now concern near ground imaging, satellite observation, ground-space and near ground optical free-space telecommunications and laser focusing.
The workshop aims at giving an overview of current research activities in this field. It will address turbulence impact and mitigation, especially in challenging environments such as strong turbulence, strong scintillation, high apparent wind speeds induced by target tracking, anisoplanatism effects due to the field of view or point-ahead angle.
The following topics will, therefore, be addressed during the workshop:
knowledge on turbulence conditions (modelling, characterization & prediction of both Cn² and wind profiles), including free atmosphere and local turbulence; study of system performance with and without mitigation; mitigation strategies based on innovative optical solutions such as single aperture adaptive optics, multi-aperture or aperture diversity solutions, integrated optics architectures, new wave-front sensing approaches, sensorless solutions, laser guide stars, high performance control; lastly, image/signal pre- and post-processing techniques (deconvolution, PSF prediction, digital communications techniques), novel reception schemes and advanced digital signal processing.

Miratlas is part of the development of disruptive New Space companies in France. By characterizing turbulence at night and during the day for the first time, Miratlas is working to address the issue of light propagation through the atmosphere.
These atmospheric measurements are crucial to ensure the continuity of optical telecommunication services between Earth and Space and address emerging challenges such as air pollution and climate change.
The workshop is supported by European Union’s Horizon 2020 research and innovation programme grant agreement 101004719: OPTICON RadioNet Pilot.
ALPAO designs and manufactures a complete range of adaptive optics components and systems for use in research and industry. Our product’s unrivalled performance enables users to recover very high-resolution images.
