Adaptive optics (AO) is a technique of precisely deforming a mirror in order to compensate for light distortion. It is used in astronomical telescopes [ 1 ] and laser communication systems to remove the effects of atmospheric distortion , in microscopy, [ 2 ] optical fabrication [ 3 ] and in retinal imaging systems [ 4 ] to reduce optical ...

Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT-SPHERE) is an adaptive optics system and coronagraphic facility at the Very Large Telescope (VLT). [1] It provides direct imaging as well as spectroscopic and polarimetric characterization of exoplanet systems. The instrument operates in the visible and near infrared, achieving ...
Deformable mirrors are used in combination with wavefront sensors and real-time control systems in adaptive optics. In 2006 they found a new use in femtosecond pulse shaping. [1] The shape of a DM can be controlled with a speed that is appropriate for compensation of dynamic aberrations present in the optical system.
As President Donald Trump approaches the first-month mark in his second term, he has moved with dizzying speed and blunt force to reorder American social and political norms and the economy while ...
Kansas City Chiefs head coach Andy Reid, center, talks to quarterback Patrick Mahomes (15) next to tight end Travis Kelce (87) before a preseason NFL football game Saturday, Aug. 10, 2024 at ...
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
