Shaping the Light with GPUs
Abstract:
Learn how GPUs are used to shape the light on extreme diameter telescopes. By providing the means to process, in real time, large-scale images from wavefront sensors, GPUs are revolutionizing adaptive optics, an instrumental technique used to compensate fast-evolving aberrations in optical systems. We'll show how GPUs are used to power the real-time controllers of these systems to provide millions of commands per second to deformable mirrors so as to stabilize the image quality at the output of a large telescope. The first results of the Green Flash project, a large-scale European initiative aimed at prototyping real-time controllers for the European Extremely Large Telescope, will be presented and illustrated with preliminary data obtained in the lab.
