Paper Abstract

Large optical telescopes (diameter 'Am) used for astronomy have a theoretical diffraction-limited angular resolution of ~0.03 arcsec. However, when used for conventional long-exposure imaging, the resolution is degraded to ~l arcsec by phase perturbations due to the Earth's atmosphere. We discuss methods to overcome this so-called "seeing" limit, with particular reference to a method based on the use of a mask in the aperture plane of the telescope. We discuss results from preliminary tests of this method.
