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

The rarely considered case of laser beam propagation and focusaing through the
moderately scattering medium was researched. A phase-only spatial light modulator (SLM) …

This paper reports a large-aperture adaptive optical system with a bimorph deformable
mirror and Shack–Hartmann wavefront sensor for aberration correction and beam focusing …

Abstract Correlating the Shack–Hartmann wave front sensor (SH-WFS) with extended
targets is widely used in solar adaptive optics systems. This paper aims to introduce a …

Atmospheric turbulence causes refractive index fluctuations that introduce extra distortions
to the wavefront of the propagated radiation. It degrades the resolution of the telescope for …

Traceable, highly accurate calibration of wavefront sensors such as Shack–Hartmann
sensors is a challenging task and an active field of research. We have developed a …

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