COAT 2025 - Communications and Observations through Atmospheric Turbulence
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.
Some presentations with permission from the author will be available to download.
