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 Fried's length r 0, the outer scale L 0, the isoplanatism θ0, the coherence time τ0, and
the profile of the optical turbulence energy are parameters of the wavefront spatiotemporal …

The Profiler of Moon Limb is a recent instrument dedicated to the monitoring of optical
turbulence profile of the atmosphere. Fluctuations of the Moon or the Sun limb allow to …

The prediction of atmospheric and turbulence conditions are important for astronomical
observations and free space optical communications. In previous papers, we have used the …

The optical turbulence measurement and characterization has become an essential
information for optical link (telecommunication, telemetry, time transfert,...) and for high …

The Generalised Differential Image Motion Monitor (GDIMM) was proposed a few years ago
as a new generation instrument for turbulence monitoring. It measures integrated …
