That work was aided immeasurably by the development of advanced, But to be able to see these fine details, Ghez had to become a pioneering user of, To overcome the issue, the new scope uses a technique from astrophysics called, Post the Definition of adaptive optics to Facebook, Share the Definition of adaptive optics on Twitter, noun, plural in form but singular or plural in construction, We Got You This Article on 'Gift' vs. 'Present'. Active optics is a technology used with reflecting telescopes developed in the 1980s, which actively shapes a telescope's mirrors to prevent deformation due to external influences such as wind, temperature, mechanical stress. adaptive optics in British English noun (functioning as singular) a technique used to increase the resolution of a ground-based astronomical telescope by counteracting the … This technique has found wide scientific applications such as the study of weather in outer planets, the hunt for small space objects such as brown dwarfs, and details about how a star is born. Adaptive optics-based technologies offer non-invasive, cellular resolution views of the living retina, and bring with them several exciting clinical applications. NFIRAOS is a multi-conjugate laser We currently offer a selection of MEMS Deformable Mirrors (DM), Piezoelectric Deformable Mirrors, Shack … In the first lecture, we saw how the seeing was the dominant factor controlling image quality for telescopes of moderate size and larger. Both Adaptive Optics and Lucky Imaging require the presence in the field of view of a reference star bright enough for the system to use to derive the wavefront errors (in the case of Adaptive Optics) or to provide an image quality indicator (in the case of Lucky Imaging). Definition of adaptive optics : a telescopic system that improves image resolution by compensating for distortions caused by atmospheric turbulence Examples of adaptive optics in a Sentence Recent Examples on the Web At around that time, a new technology, adaptive optics (AO), was being installed on telescopes worldwide. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! Test Your Knowledge - and learn some interesting things along the way. With Adaptive Optics it is imperative to run the wavefront sensor much faster than the characteristic seeing timescale so that the system can effectively compensate for the seeing before it all changes again. Adaptive optics (AO) The degree of correction of an adaptive optics system is frequently quantified by the "Strehl ratio", which is the peak on-axis intensity of the actual image of a point source, divided by the peak intensity which that same source would have if the telescope were diffraction-limited. As light from distant celestial objects enters our atmosphere it gets disturbed by our ever-moving atmosphere. Adaptive optics (AO) enables astronomers to counteract the blurring effects of turbulence in Earth's atmosphere, which degrades images seen by ground-based telescopes. Build a city of skyscrapers—one synonym at a time. More from Merriam-Webster on adaptive optics, Britannica.com: Encyclopedia article about adaptive optics. The team is led by NRC Herzberg As tronomy and Astrophysics, based in … The name Active Optics refers to a system that keeps a mirror (usually the primary) in its optimal shape against all environmental factors. Send us feedback. • “Adaptive optics, a technique used to overcome blur in ground- based telescopes, can also overcome blur in the eye, allowing the sharpest images ever taken of the living retina.” The opening line of any book should say, in the words of Stephen King, “Listen. “Adaptive optics.” Merriam-Webster.com Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/adaptive%20optics. First, light enters a detector that determines the shape of the wave fronts. With adaptive optics, however, astronomers are already able to replicate the sharpness the Hubble telescope can produce.
