The atmospheric turbulence that distorts the trajectory of lights rays have been a source of frustration for astronomers using huge telescopes.
Damien Gratadour, an associate professor at Université Paris Diderot, was at the GPU Technology Conference last month to talk about how his team is using NVIDIA GPUs to reshape light beams so astronomers can get images that are as sharp as possible out of large telescopes like the European Extremely Large Telescope (E-ELT) — currently under construction and due to become operational in 2024.
