It will be possible to observe to fainter magnitude limits and, with adaptive optics, with higher angular resolution due to the sizes of the primary mirrors. In addition it is expected that "quantitative techniques" such as astrometry and photometry will achieve levels of accuracy not possible today. This requires controlling the error sources affecting such measurements, for example distortions caused by all parts of the optics, to a higher level of accuracy for much larger components than on current telescopes. It might also be necessary to adapt calibration procedures and observing techniques in some cases. In this talk I will give an overview over the challenges this presents for the design, construction and operation of ELTs, concentrating on the example of precision astrometry.</p></div> https://ao4elt2.lesia.obspm.fr/spip.php?article720 https://ao4elt2.lesia.obspm.fr/spip.php?article720 2011-07-05T09:54:29Z text/html en Luc SIMARD Submitted by L. Simard Authors Luc Simard Affiliations NRC-HIA Abstract Many critical observations are simply beyond our present 8-10m telescopes due to photon starvation and limited spatial resolution. These obstacles will be overcome by new adaptive optics systems on extremely large telescopes that will provide huge gains in in sensitivity, contrast and angular resolution and fully realize the so-called "D^4" advantage.

In this talk, I will discuss a range of science cases going from the surface of outer Solar System bodies to the First Light objects in the Universe where AO on ELTs will have a particularly high impact and the potential for exciting new discoveries.</p></div>
