Scientific paper

In addition to improving the angular resolution of solar and stellar observations, the application of adaptive optics to astronomical telescopes will improve the contrast of pointlike sources against both sky and telescopic apparatus thermal backgrounds, enhance spectroscopic resolution, and increase the sensitivity of optical interferometry. Performance projections are made for a prospective 8 m aperture telescope incorporating wavefront sensor-based adaptive mirror and digital servocontrol systems; results comparable to those of space-based telescopes appear obtainable, albeit at atmospherically transmissible wavelengths. The development status and focus of the various current programs in astronomical adaptive optics are noted.
