The forecast for atmospheric and turbulence conditions above astronomical observatories is
of interest to the astronomical community because it allows observations to be planned with …

The performance of ground-based astronomical observations and free-space optical
communication (FSOC) systems suffers from atmospheric turbulence and meteorological …

The future generation of extremely large telescopes will be certainly equipped with wide-
field adaptive optics systems. All the components of such adaptive optics systems have to be …

We present a generalized differential image motion monitor (GDIMM). It is a compact
instrument dedicated to the measurement of four parameters of optical turbulence: seeing …

Atmospheric turbulence reduces the image quality and resolution of ground-based optical
telescopes. Future large solar telescopes (eg the CGST, China Giant Solar Telescope) …

The structural characteristic of the refractive index of optical waves was calculated from
experimental data on the microstructure of the temperature turbulence in the atmospheric …

Dome seeing is a known source of image quality degradation for any telescope, but despite
tremendous progress in wavefront control through the development of adaptive optics and …

For the new generation of Extremely Large Telescopes the knowledge of atmospheric
turbulence conditions is become an information of primary importance to design and …

The Atmospheric moNitoring to Assess the availability of Optical LInks through the
Atmosphere (ANAtOLIA) is a station developed in the framework of a project funded by the …

To reach a high performance with an adaptive optics system, we need a calibration using a
reference source. This latter should be located in the same isoplanatic domain as the …
