Adaptive Optics for Future Extremely Large Telescopes Prof. Richard Myers (University of Durham)
All talks start at 7.30pm in the Royal Society of Edinburgh, 22 - 26 George Street, with refreshments from 7.00 pm
Abstract: Adaptive Optics can be used to compensate for the effects of atmospheric turbulence on the imaging performance of ground-based telescopes. This technology is optional for existing 4-8m telescopes, but will become mandatory for the future 25-39m telescopes. We will look at the astronomical drivers for these new facilities and how the consequent need for adaptive optics impacts on their designs. Substantially new forms of adaptive optics will be required to perform the main scientific missions and we will examine the current state of development, which has included on-sky technology prototyping. We will look in particular at the results from the France-UK CANARY adaptive optics demonstrator, which provides a scaled model of two of the new adaptive optics modes of the 39m European Extremely Large Telescope on the 4.2m William Herschel Telescope. CANARY has been developed by a collaboration including Durham University, Observatoire de Paris and the UK Astronomy Technology Centre in Edinburgh.
