The hybrid model for analyzing distortions of a laser beam passed through a moderately
scattering medium with the number of scattering events up to 10 is developed and …

Atmospheric turbulence causes refractive index fluctuations, which in turn introduce extra
distortions to the wavefront of the propagated radiation. It ultimately degrades telescope …

The search for exoplanets has discovered thousands of worlds orbiting stars other than our
own. To learn more about these worlds, it is necessary to directly image them and study their …

A metrological device—Hartmannometer—based on a Shack-Hartmann wavefront sensor
for measuring the flatness of optical surfaces was developed and researched, and the …

A multispectral wavefront sensor can be used to perform a single-shot spatio-temporal
characterization of a laser pulse. In order to measure the spatio-spectral electric field, a laser …

Adaptive optics (AO) provide real-time compensation for atmospheric turbulence to improve
the resolution of images acquired by ground-based optical telescopes. The actuators in …

Advancements in optical imaging are needed to study vision robbing diseases. New
technology can be developed using animal models, which can progress the understanding …

Le développement technologique continu et rapide des lasers a ouvert la route vers des
puissances crêtes et moyennes élevées et des régimes d'interaction laser-matière …

Wavefront sensing is a powerful technique to assess and quantify the aberrations present in
optical systems. Turning this idea around and assuming an ideal optical system, it can also …
