Keck Observatory to Update Adaptive Optics on Keck II Telescope

Facebook X LinkedIn Email
The National Science Foundation (NSF) has awarded funding to the W.M. Keck Observatory on Maunakea, Hawaii, for a significant enhancement of the performance of the adaptive optics (AO) system on the Keck II telescope. "The Keck telescopes were the first large telescopes to be equipped with AOs and subsequently laser guide stars,” said Peter Wizinowich, principal investigator and chief of technical development at the Keck Observatory. “All major astronomical telescopes now have laser guide star AO systems. Despite this competition, Keck Observatory's AO systems have remained...Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
